Durable and Reusable Cardboard Rivet

There are a lot of printable cardboard screws out there, but they all print in an orientation not suitable for strength or durability - almost all of them have comments about being difficult to print or breaking on the very fist use. My kids are making cardboard shields by stacking up a several sheets, so I wanted a way to bolt them together that would also let them stand up to being used. So I made a three-piece parametric rivet/clip that you can adjust the depth of the clip. Prints with no supports and no overhangs. The provided print profile has a 10mm rivet (which is just right for four layers of Ikea flatpack cardboard, by the way). Plates 1-3 are the individual pieces so you can tell Handy how many you want to print at once if you want to use multiple colors. If you want everything one color, Plate 5 has all three pieces. Plate 4 is the cutting guide, which you don't have to print but does make the job easier! I'd suggest using a more pliable material. PLA Basic was rathe
