I wanted my electronics in the back so it also hid the cables and could have easier cable management.
There is one folder with just a blank plate, my layout is for a SKR pico, Rpi zero 2w, 40mm cooling fan and uses M5x8mm bolts and then one step files if you want to make your own configuration.
Since the backplate is 240x210mm, I also made 2 and 4 piece to fit more printers. For the blank plates and STEP files, there are M3, M4 and M5 versions so you can print them right away!
Didn't realize that the 3mf files would keep the black color from CAD, apologies for that.
The author marked this model as their own original creation.
