The file 'Ender 3 Dual Rail Raspberry Pi 4 30mm Fan, Lid With MX Keyswitch Hole 3D Printer Model' is (stl) file type, size is 504.7KB.
I wanted to add a shutdown button for my Pi 4, so I added a hole to fit a regular mechanical keyboard switch. This way I could use what I have laying around instead of ordering like 40 buttons when I only needed one.
This is also the version that fits a 30mm fan.
