Original idea was taken from https://www.thingiverse.com/thing:2317482
But I redesigned it so that it would be possible to put a damper with the stepper. There you can put Nema 17 with a height of 42 without a damper or a height of 34 or less with a damper. For the double z-axis, it can be mirrored in the slicer. There are three options, with air vents and without, and cutout for Z-frame.
Now I use a manually fixed prototype, I'm too lazy and do not have a cheap filament to reprint it, so... :)
I have printed it using PLA.
