Fast Fusion 360 - Snap Fit Parts for 3D Printing

i'm going to give you a quick overview of snap fit joints here these are simple snap fit joints i've already created a box and a lid and basically with a snap fit joint you're here using the extrude tool with tapered angles so i've already created a sketch the sketch is going to be two millimeters high by six millimeters wide and i'm using the midpoint tool to center that sketch and next i'm going to extrude by two millimeters and then give it a taper angle and the taper angle use negative 45 degrees be sure to use negative because if you don't you're going to end up with a big trapezoid coming out of your lid we're going to put a fillet on this but before that we're going to construct a midplane so that we can use the mirror tool and replicate that snap part to the other side of the lid so now that we've created the mid plane i'm going to add the fillet and here i'm going to use 0.4 millimeters i'm using a creality ender 3 pro with esun pla and a 0.2 millimeter nozzle and that 0.4 millimeter fillet does the job i'm going to mirror the snap fit part and the fillet to the other side of the lid and after this we're going to work on the box we've switched from the lid to the box and we're going to use the sketch from the lid to make the snap fit part on the box and if we rotate the cube here you'll see that the sketch is offset from the box by 0.2 millimeters and you want to have some offset between your two parts so that they will come together nicely so i'm selecting the sketch and i'm entering a distance of two millimeters and an extrude taper angle of negative 45 degrees again to match the snap fit on the lid i'm going to add a chamfer of 0.6 millimeters that chamfer will help when you're pressing the lid onto the box otherwise you're going to have a tough time getting the lid on the box we're going to mirror the snap fit part from the box onto both sides and we're going to include the chamfer as we mirror the snap pit part using the features and then we're going to shell the box and i'm going to use a two millimeter inside thickness and that seems to print well we'll use the section analysis tool and if we take a look inside you'll see the offset where we have a 0.2 millimeter offset between the lid and the box and how the chamfer and fill it come together again with that 0.2 millimeter offset it comes together nicely it's a tight fit it takes a little bit of effort to get it off you may want to experiment with your offset between your objects experiment with your fillet size with your chamfer and to get it dialed in with the printer and material that you use all right that's a quick overview of snap fit joints have a beautiful day
