5mm Hex Holder

This is a simple 5mm hex key holder mounted to a spare hole on my fiber laser. The groove is sized for a 5mm hex key to slide in and the hole is sized for an M6 bolt to screw into the fiber laser tower. My laser's bed is drilled out for M6 screws to hold fixtures and having a 5mm hex key nearby is super handy. Created in Tinkercad because I originally thought this would be a simple model. Well, 3 revisions later, I probably should have used OnShape or Fusion because Tinkercad did not allow me to edit dimensions parametrically. I had to redraw the design multiple times.
