A small keychain with rotateable gears. Two versions: a square version and a zigzag version How to make: see instructions Edit: added a version with smaller clearances and added also the SolidWorks files Instructions Step 1) Print 3 gears Step 2) Print the holder and the dummy at same time Step 3) Pause the 3D-printer when the printhead is located at the dummy and just before the bridge structure of the holder is going to be printed Step 4) Place the gears ( make sure that the dummy s located far enough of the holder so that you can place the gears) Step 5) Continue the print Step 6) Your keychain is ready ( I have printed it with a prusa i3 / layer height: 0.2mm / 0.5 mm nozzle)
