Multiboard custom shelves. Created from the Multiboard Pegboard Click Hook to quickly change the arrangment as needed but also be sturdy to hold weight. I added a 3U and a 4U shelf, sliders are the same.

Printed with standard Multiboard settings 0.2mm layer height, 3 walls, 15% Infill, no supports
