For holding 3" abrasive cut off wheels. Hole is 3.1" diameter.
The author remixed this model.
I wanted one slightly taller, and without the center post. I made it this size to maximize the number of disks I could hold in my shallow drawers, while staying with whole number height units, and not waste space with the stacking parts. I technically made my version from scratch, but was inspired by the linked model.
This bin prints 49mm high. The main hole is 3.1" diameter, to give more clearance for the wheels. Non Stackable.
