125mm Sanding Disc Holder

Heavily inspired by this project:

But remade from scratch to fit the multiboard mounting system and made them stackable with the multiboard mountingpoint layout. 

Also removed some of the materials and it prints in about ~2,5 hours on my prusa mini Including the 2 T-bolts :

So it can be screwed right into the panels

Otherwise printed with 3 perimeters and 15% infill
