My 4" Dust Collector hose kept getting in my CNC's way and the bungee cords were not cutting it anymore, so I made this carriage to ride on some 3/4" EMT and keep it out of the way.

Carriage is made of 3D printed body, (3) 608 Bearings, (3) 1" 5/16 Bolts, (3) 5/16 Nuts, and (2) 5/16 Washers.

If you want to print your own, head on over to the blog and grab the .stl!
