The file 'Steam Deck Carrying Case Generic Insert 3D Printer Model' is (stl) file type, size is 51.4KB.
So I didn't like other compartment insert designs so I made my own.
The design is "non-opinionated", it's only purpose is to keep things from falling out.
TPU is the recommended printing material.
Designed with Fusion 360 for personal use
