All plastics were designed in Fusion 360, and appropriate archive files have been uploaded.
To print, download all 4 STL files and feed them into your slicer of choice. You can use an online printing service, but be aware of the warning below.
These parts were originally designed with ABS shrinkage in mind, and before uploading were rescaled (to 95.3%) for PETG based on some test runs. You may need to tweak the scaling to get a good fit across all your parts.
