About this 3D model
A simple rack that holds several rolls of filament at a good height to load directly into my Ender 3 extruder. Used 1/2 inch PVC because I had some spare lengths. In this picture I printed the insert and left it on the build plate before swapping my filament and printing the body directly over it to get a good solis bond between the pieces. I also printed the body with zero top and bottom layers so I could see the infill for a lattice effect, but I think the part pieces are too thin to make this effect come across.
