Show your appreciation by taking a picture of your creation and posting it as an "I made one"! It'll be fantastic! 😃 The keychain's 12mm ball adds charm to its design. I inserted the ball mid-print. This keychain is based on the coin trap, which you can find at http://www.123dapp.com/123D_Design/knikker-doosje-2/2381130. In my previous attempt, I designed it using 123D Design Online, a program now discontinued by Autodesk. Consequently, I can't share the file anymore. The software allowed me to create shapes by dragging and dropping them, with an additional feature to chamfer everything for a smooth appearance. To avoid the extruder hitting the marble, ensure that the box height is high enough so that the printed box is at least 1mm taller than the marble. Back then, I had to get it right in one try due to lack of a pause function. Now, you can use the pause feature to check if the print's height is sufficient. Additionally, search for the ideal marble and adjust the box size accordingly for a perfect fit.
