First stab at a holder for sandpaper
Some refactoring, slightly less wide
First trial print: Has edges and studs
Trial print 1 of lid/top
Added todos
Added extra spacing to grib
Second print: Ergonomic holder, butterfly nut, etc
Removed some todos, debug for cylinder
Print 3: Slightly larger nut, moved butterfly
Print 3 works on my printer. Very nice indeed
