The Tallest & Tiniest Twist Containers Ever!

tablet laptop or phone hey guys it's Devin here with make anything and in front of me we have a lot of parts that will hopefully come together to become the tallest twist container that's ever been made Dustin the Jackman and Joel's a 3d printing nerd already made some pretty giant twist containers on their massive printers and I wanted to keep the ball rolling but I don't have a printer as big as theirs so I decided to try a different approach these parts are modular meaning they can stack on top of each other pretty much infinitely to make a really tall - its container I'm hoping everything stacks together really well and makes a nice straight container that way I can have that super satisfying slow twist down as I stick the two halves together so today we're going to do that we're going to stack all this together and try to make a super tall twist container and you know I'm also going to try to make the smallest possible twist container just because it's fun to try all the extremes right well I'm super eager to get this working so let's get right to it here you can see me printing the pieces for the outer container on the flux Delta plus and I'm using rigid ink PLA the walls of these containers are less than one millimeter thick and they printed just great using flux to do with the cure to setting for the slicer these intersections were printed on my bc n sigma using Florian's eco-friendly plastic and as you can see these pieces just slide right together to create a seamless wall so this inner container is designed so that the outside surface is the smooth one and the connectors are all on the inside while this outer container have the connectors on the outside so that the inside surface is seamless that way the surfaces are as smooth as possible where these two containers are sliding past one another so here I'm testing out a shorter section of this twist container it's still very tall but I'm planning on going much taller yes from the looks of this early test everything's working really well and that got me super excited I would like these to twist together a little bit slower but I'm kind of expecting that to happen as I make the container longer while these parts do snap together with a pretty tight fit I decided to use my 3d pen to weld the parts together to make sure that they're really sturdy and stay stuck together so to keep the outer surface of this container smooth I went ahead and welded it together from the inside just creating some small lines that join the scenes together just enough to hold it in place and I just continued that pattern as the TWiT container grew adding one piece at a time and welding them together until I had a twist container that was taller than me as I was finishing off I realized that this end cap should have been my starting point since I won't be able to reach the inside to stick them together but it's strong enough fit that I think it'll be okay so let's use one of these outer sections and see if this will slide all the way down well I couldn't have asked for it to go much better than that so I went ahead and started assembling the outer twist container this one I also fuse together with my 3doodler but from the outside since that's the part that's not touching the other container I just created these little stitches on three of the six sides as I figured that's enough to hold it in place the bond created by fusing parts together like this is pretty strong so I wasn't too worried stacked on top of each other these containers reach nearly 14 feet tall I think it's safe to say that's the tallest twist container around but at this ridiculous height will the parts still slide together let's see sure enough that outer container slid all the way down although that inner container did get a bit stuck so I have to really shake it to get it out but just look at that it is a sight to behold no hands to unfortunately when I took this outside to get the whole thing in frame the winds just knocked it over and they kind of broke into several pieces and cracked at several points as well so I had to take it inside again and use it back together this time around the container was too long for me to actually reach inside and fuse it together from the inside so I had to weld it together from the outside but I was just really careful to squeeze the plastic in between those cracks to keep that surface as smooth as possible I actually ended up welding all the seams of every connection on both the inner and outer parts just to keep the air from escaping from between those seams and hopefully making the whole thing twist down a little bit slower but that done I went ahead and gave it another test run and as you can see it actually did slow down significantly but as you can see it's pretty unstable so my next step was to create some sort of a base and I did that by just using this scrap panel of wood and then stapling down this raft from one of the parts that I printed so with that firmly attached I'm going to go ahead and use my 3doodler with this external battery so that I can use it here outdoors it just clips on and I'm going to go ahead and weld the entire inner container down to this raft and hopefully that'll make it nice and sturdy and stable I tested that connection with a sketchy tilt test and look at that pretty darn strong but I still felt like I could do something a little more add something special you know like this thing so this is a melodica and I wanted to see if I could attach this to the top of the outer container and actually have the container play some music as it was twisting down it's a crazy idea but hey sometimes crazy works so I went ahead and took my 3doodler and just melted a hole in the top of that container to match the size of the mouthpiece for my melodica so I'm not actually extruding any plastic here I'm just using the heat of the nozzle to melt away this hole once I have it the right size I went ahead and just stuck the melodica on top of there and that actually fit pretty well but I think I still need to add some structure to make sure this is sturdy so I'm going to wrap some tape around the bottom here just so that I don't end up damaging my instrument and then I'm going to use my 3d pen to create a support structure connecting the melodica to the twist container itself I went ahead and created this kind of trust support on all sides and it seems pretty strong now I'm just going to go ahead and tape down one of these keys and hopefully enough air will be pushed through this instrument to create a sound well there you go I think I just invented a new and wildly inefficient instrument let's go ahead and tape down some more notes and see if we can play a full chord now the twist container itself is already really loud and that's why I have to hold my microphone up so you can actually hear the notes being played I won't try to argue that it's playing any beautiful music but hey it is in fact playing music after a couple attempts of this the wind just ripped the containers off of the bass but maybe I could use this in a sort of different way and actually play some notes [Music] [Music] [Applause] [Music] all right this is ridiculously tiring and sounds pretty terrible but hey this is how discoveries are made right so to do a little bit more testing I ripped this thing off took off my support structure and I'm going to try playing it in a slightly different way by connecting this hose instead and then dropping the container from above yeah still far from amazing but it was worth a shot hold up I was thinking maybe we should take a minute to talk about what the actual forces are at play with these twist containers what is causing this super slow and satisfying opening and closing and why am I able to play music with a twist container to some it might seem obvious but I was actually really interested in the sheer number of different principles that are at play that caused this twist container to work the way it does in order to better understand what's happening within my own creation I decided to go ahead and visit the great courses plus for a little bit of a refresher they have this really awesome 30 hour course called physics and our universe and I was particularly interested in lecture 20 about fluid dynamics which kind of explains some of what's happening here all of these containers whether they're giant or tiny contain air inside of them and when the container opens the volume of air inside increases so air has to get inside and when it closes the opposite happens the air has to get out so when I closed one of these twist containers the air has to escape mostly through these tiny little spaces in between the two containers and because that space is so tight the rate at which the air exit is limited that's why we get a nice slow fall and because those air molecules are occupying that space inside you can learn some really interesting things for example if I close this twist container really quickly I'm actually compressing the air inside of that container and it's heating up and when I pull it apart quickly I'm starting to create a vacuum by increasing the volume quicker than the air can get back in there it's kind of stretching out the space as the air molecule can take out so when I create that tiny hole on the top of the container all that air occupying that large column has to squeeze through the tiny little holes as well as the other exits but it's really pushing through that hole increasing in magnitude and therefore having the strength to play them a lot attacked it's pretty cool stuff on top of being slowed down by the displacement of air these containers are also slowed down because some of the energy in the container falling down is converted into rotational energy as this thing is twisting and if you think about it the container isn't falling straight down now it's kind of falling at an angle along the ridges of this twist container it's like comparing a ball that's falling down a super steep hill really quickly versus a really shallow hill where it's going to fall down slower that's kind of happening here as well as of course friction friction between the layers of the print see there's all kind of stuff happening I think I've got that right mostly I don't know I've really complete that 30-hour chorus by Professor Wolfson because it's really fascinating you know by learning about the way things move and what causes certain motion you can better manipulate it and when I'm doing the kinds of stuff that I do that's really useful information I might be able to figure out some very interesting ways to create non-intuitive motions from things that I say be print if you guys aren't familiar with the great courses plus it's definitely worth checking out it is this online on-demand video subscription service that gives you access to 7,000 videos about all kinds of different things that might interest you all these courses are taught very respected people like Ivy League professors or experts from the National Geographic the Smithsonian the Culinary Institute that physics lecture was super helpful and I'm also really excited to check out the courses on photography and playing guitar maybe some cooking if any of this sounds interesting to you you should definitely visit the great courses plus slash make anything or visit the link in the description you can get a one-month free trial so you got nothing to lose and a lot to learn beyond that courses start for as low as $14.99 a month not a bad price for infinite knowledge nearly all right so now that we've had that little informal physics lesson let's see if we can make some really tiny twist containers you know how is it going to be affected by the fact that there's a lot less air to displace a lot more friction relative to the size of the whole thing I don't know just try it out first off I want to share these pretty tiny containers that were actually made during my visit to Autodesk's pr9 creative workshop these were printed on their commercial grade printers so the tolerances are really good and the layer lines are nearly invisible unfortunately the way these are printed is that they're suspended in a kind of waxy support structure and I wasn't able to completely get rid of that waxy coating so that kind of prevented it from really sliding together the way my twist containers are known to do so I decided to take things into my own hands and try making some even tinier twist containers on my own replicator 2 3d printer the first thing I did was swap out the standard point four millimeter nozzle with a smaller 0.2 millimeter nozzle and that's going to help me create thinner walls and make everything just that much smaller then I printed out these really tiny containers using vase mode which basically means that the entire thing is being printed in a single upward spiral instead of individual layers and that's going to help me make the part as seamless as possible now at this small of a scale even a fraction of a millimeter difference Lawrence is going to affect the containers so I actually had to print several of these in hopes of finding two that twisted together really well and this is the smallest that I was able to come up with the outer container here is a mere four and a half millimeters wide and while they twist together they still don't really slide together and I don't think it's a proper twist container unless it actually slides together on his own so I decided to scale up just a bit and I created this soft twist container this works a little bit better but it's still a little finicky and I don't think I would necessarily call it satisfying but after some more experimentation I was actually able to create a smaller twist container that truly works at only eight point three millimeters wide and ten point four millimeters tall this thing actually fall down and twists on his own so I'll go ahead and say this is a proper twist container and it's properly tiny alright guys well that was a really fun video for me to make we made some giant twist containers as well as some really tiny ones to projects that are kind of related and yet so vastly different that it's hard for me to show both of them on the same screen it's always fun to play with extremes taking a regular object and seeing how big you can make it on how tiny it can get so if you guys have any ideas of other objects that I can make really big or tiny let me know and it might end up in a future video but that's it for now so I hope you liked it and until next time I'm Devin this is make anything don't forget to stay inspired you [Music] you
