Angle Grinder Disc Holder 100mm 115mm 125mm – Wall & Bench Mount

A practical 3D printable angle grinder disc storage holder designed to keep grinding, cutting and flap discs organised and easy to reach.

The holder accepts both 100 mm and 125 mm angle grinder discs, so you don't need separate holders for different disc sizes.

It can be mounted vertically on a wall or horizontally on a bench, shelf or work surface. The long central spindle keeps multiple discs together while still allowing them to be removed quickly.

Ideal for workshops, garages, fabrication shops, welding areas and tool storage.

This makes the same model useful in different workshop layouts.
