About this 3D model

This very simple spool holder bracket was designed to hold my filament rolls, by mounting a length of 20mm HDPE pipe, inside a plastic box (to protect the filament from moisture). I went for this design because it was simple, and used HDPE pipe that I had laying around, which is nice and low friction, so we had been using it as a dodgy pipe support when we first got the printer running. I have included designs for open or closed brackets. The open bracket allows you to take the spool out without unbolting the brackets. Accepts up to 21-22mm diameter pipe/rod, and uses M5 mounting bolts.
