Wall mounted bins to hold 150mm or 6" sanding discs. 

Find the 5" version here.

I liked a lot of the other options out there, but I wanted to make some improvements:

• Easy change labels in 2 colors - only a single filament change
• Ergonomic handle with adjacent thumb hole (you may want to mirror the bins if you're left handed)
• Lid to stop dust settling
• All 3d printed - no dowel or metal  rod needed

Notes:

• Actual bin diameter is 159mm
• When printing the top bracket with the attached lid, make sure the part fully cools before removing from the plate to avoid it curving
• The font on the labels is 12mm Arial if you need to make something custom to match
