UPDATE Feb. 28, 2024: Updated the QR generation code from github. There was a bug in that code that is now fixed. Be sure to check the QR code on screen with your phone before printing to ensure correct QR code generation.
14 minute print on Mk4 Input Shaper!
Use the OpenSCAD customizer to enter your Printables ID and adjust the key fob size. Then render, and write out the STL file.
PrusaSlicer is excellent at detecting the need for color change, so it's really easy to get a nice result.
Note on size: You can probably print a bit smaller than 40mm, but you'll need to edit the code directly, or scale in PrusaSlicer. I tried 25mm, and the QR code was not readable.
Don't hesitate to request model tweaks👍, and thanks to “like” 💟, download, and share your “make”⭐.
