modular Gridfinity boxes that fit Multiboard or screw onto the wall.

available in 3 sizes 50, 75 and 100 mm in height, and you can build it however you want, with any sizes you want.
it fits 4 gridfinity boxes in width per box.
size 50 can handle gridfinity boxes up to 5 u
size 75 can handle gridfinity boxes up to 8 u
size 100 can handle gridfinity boxes up to 12 u

the mounting holes are adjusted in size so that they fit multiboard, and I have used the original screw for multiboard: [https://thangs.com/designer/Multiboard/3d-model/13%2520mm%2520Small%2520Thread%252C%2520Flat%2520Head%252C%2520T-Bolt-974236](https://thangs.com/designer/Multiboard/3d-model/13%2520mm%2520Small%2520Thread%252C%2520Flat%2520Head%252C%2520T-Bolt-974236)

I can recommend testing this screwdriver that Paradox69 has made, to make it easier to access and screw in the screw: [https://makerworld.com/en/models/559109?from=search#profileId-478285](https://makerworld.com/en/models/559109?from=search#profileId-478285)
