Arduino Prototyping Physical Frame

Recently I've returned to working with arduino and similiar modules, and got quickly fed-up with cable mess on the table, having everything connected with cables, lying loosely.

Being unhappy with ready-to-print things I've found out on the internet, because most of them required either aluminium spacers, were too simple-minded forcing me to use certain layout and nothing else, or beign straight up 25x25cm flat printed board, I've decided to delegate some of my time to make my own "system" of customisable frame for arduino prototyping, so everything could stay in one place, at the expense of few hours of printing.

Files include modules for:
frame part itself
vertical stands for 2,3,4 level frames
inserts for arduino mega
inserts for arduino uno
inserts for various PCB / breadboards
inserts for step down converters

Probably more to come, but dont expect them soon.

OBJ files, as exported from my 3d app. Should import fine in any slicer or 3d application like 3ds max or
