It is simple, I used to print it on PRUSA MINI+, with PETD.
print two times holder 1 & 2, then once cover_btm and cover_up.
After print, just screw holders and bottom with screws M5 (allen) through, 4x screw.
Size is for MI MIX3, and Yamaha TDM850 4TX, but if you want, feel free to modify models if you like it. Parts are in FreeCAD.
Sorry for bad photos, but still in printing.
