Mic stand design from scratch - CAD tutorial

all right guys so you click the video for a microphone stand I just started my patreon and I have this really cool USB microphone but right now I don't have any any way to really hold it in place so I figured let's make a video on how I'm going to 3D print a cool little microphone stand it's going to be really basic I'm going to try and get it all done in this one video top to bottom so I'll show you how to do that and if you want the file you can download it it'll be on the page so first off I'm using my cat software it's Creo 10.0 and you can use whatever CAD software you like this is just what I happen to be using so I'm going to just get right into it all right so we have our working directory set we're going to hit new it's going to be a part I'm going to call it Mike stand one okay I have the default template set to millimeters because that's what I prefer metric system works really well okay so let's go we're making a microphone stand I want this microphone stand first we're g to we're going to figure out a few of the the uh different uh features I want it to have like an angle to it I don't really need that angle to be adjustable but I need the microphone to kind of face up at me and it needs to fully support itself so I'm going to start with making an offset plane to raise this microphone off of off of the surface so we're going to pretend that this top plane is the surface of the table I'm going to create a plane let's say 50 mm up I'm going just grab my caler see how that looks I'm holding the microphone so sorry if you have hear some noises here okay actually it's got pretty long cord on it so I'm G to shoot for let's go like 75 millimeters up uh is where it's going to start clamping on the on the microphone and this is just a plane that's going to establish that it's really important that you get your plane set up before you start designing because this is going to help with your design okay so like I said we want this microphone to tilt towards me so I'm going to go on the front plane and on the plane that I just made and create an axis you can see this axis right here it's running perpendicular so we can create an angled Plane off of the plane that we just made and let's tilt it back like this so we're going to kind of imagine that the microphone is on this plane and it is embedded into the plane and this is what's tilting the microphone this is what is driving that angle so let's just set it to 115 actually I'm thinking a little more 120 looks pretty good and we can always adjust that after the fact okay so now we're going to start drawing some geometry so I'm going to save this part real quick we're going to add some geometry so I would like um it to just slip into place and um I don't really want it to clamp in or anything crazy so let's just start with um let's start with a round circular bottom and we'll go from there so I'm going to draw make an extrude feature and since this is tilting we're going to want to support it from the back so I'm going to make this kind of stand offset from the front plane and the diameter let's make it just slightly larger than the actual microphone the microphone itself is exactly 43 .7 so we'll remember that for later let's make it 50 in diameter so we'll type 50 we have it centered on this plane and let's constrain a distance away from the front let's say like 30 and we can adjust that later so this is going to come up and this is going to support the cylinder holding in the microphone so I'm going to start that there I might actually um do this feature second I want to establish a round feature that's cradling the mic first so let's create another axis and do a revolve feature so I'm going to create an axis on this plane and this plane and it's going to be an angled axis and this is going to be the center of where the microphone sits so let's do a revolve feature on this plane we're going to center it and it just flipped it backwards so we're going to flip it correctly and right side up sketch okay I'm going to grab this awesome axis that we created that was the Tilt so that we can establish an X axis or an X reference plane I mean okay so let's make a cylinder so we we with a revolve feature we need a center line and we need a rectangle let's make this rectangle like this and it was like what was it 46.7 so let's define that at like was it 43.7 that's measure it again yeah it was 43.7 so let's make it 45 make it a little comfortable actually we kind of want it to flex right let's make it let's make it uh 43 okay and the thickness is let's make it 3 mil let's make it uh like a sleeve like 50 mm High I'm going to grab these dimensions and I'm going to lock them this means that we can't adjust them anymore unless we write the numbers in and it looks like the only defined measurement we need left is the height of the clamp so let's put it like 10 mm above this reference plane and as you can see it populated and filled out this awesome cylinder and we can control that Dimension that we didn't lock so we can adjust it as needed so let's let's go ahead and make it a little bit taller I'm thinking a 50 is good actually 50 is perfect let's roll with that and now let's bring this other feature back in so I'm thinking I want this to have a smaller diameter and we want it to meet up with this so that looks decent but we kind of want want it to kind of encapsulate the whole thing like this so this will be the main support leg and we're going to do it to next so it should terminate once it reaches that so I'm going to hit okay save that and let's make a little round to pretty this up let's see if this will this will solve here looks like the circle isn't quite in a very good spot so let's edit that let's bring it further up this way there we go that looks better now let's add this round feature populate that blend it make it look real nice that looks pretty good okay so we have the base and we have the microphone it's going to sit in here um now we want this cup to open up for me so I'm going to make an extrude and we're basically just going to um reference these two lines reference the tap and we're going to cut this section out like a little width of it so I'm going to do a slanted rectangle grab that grab that okay now we're going to do it symmetrical remove material looks like since it is a round feature let's try it again instead I'm just going to grab this and this going to make this rectangle on this surface and we're just going to pull it out into Infinity this will work just fine let's make it a 5 mm cut so it can kind of stretch or I guess we can make it like two because it's going to flex outward so that looks pretty good now we just need to make sure that it is going to not tip over so we're going to add some awesome legs to the bottom so let's do an extrude feature on this and let's grab my circle there reference the circle now we know exactly where the center of it is and what the heck let's just make it another just a circle I think the center of gravity should be okay let's make it 70 and let's make it 3 mm tall just like that hm this should support it just fine I'm thinking we'll be cool with that and if not we can edit the design later so now we're going to make this look really pretty I'm going to add another round feature let's do 15 there let's do two here actually let's make it one and then I can add some rounds to all of these surfaces so we'll make these all kind of clean make it insert clean round this round this and let's even round oh let's see I think that's actually going to fail so let's just round these we can keep the bottom kind of straight so that's where the microphone wire is going to come out um this looks kind of dumb being that intense that is going to strengthen it so let's maybe bring it to 10 let's just make it a radius of 10 and I don't want this base to break off it kind of looks like it could because of this shaft being so skinny so what I'm going to do is I'm going to actually design uh a screw to go through this um I have some machine screws that are 3 inches long and I'm kind of dumb I can't remember what 3 in is in millimeters let me Google that 3 in to mm at 76 oh so that's literally perfect so I'm going to make another extrude on the bottom we're going to grab the center axis I'm going to make a circle um I believe that the screw has a diameter of it's um 3.7 so I'm going to make I'm going to make this whole 3.5 and then the threads should cut and it shouldn't be too tight um we should still be able to install that screw into the base and we're going to run that um through all let's see if through all yeah that looks good that runs all the way through that microphone area uh let me just double check that this is not going to be too high I mean make sure that the screw is not going to go all the way through into the microphone area all right perfect we have 82 mm in height from the hole to the base so now I'm going to add a chamfer because it's a chamfered screw we need to add it to that and let's make the champer like pretty aggressive so we want that to go all the way so let's make it 3 mm that looks pretty good now that screws to run all the way through it'll keep it from breaking off we can hold the microphone plenty of room for that stuff and if I need I can add like an awesome like a padding to the bottom like a foam thing so it can slide or rubber grip whatever adhesive kind of thing so I think our Design's done so let's hit saved let's 3D print this bad boy and I will post a picture of this final product and I will also put the STL file for you to print in uh my patreon
