Description

PDF

I present to you a model that will help you reduce print setup time or filament replacement during printing. I recommend printing this model with a layer height of 0.2 mm, a minimum of 3 perimeters, gyroid infill, and an infill density of 35-45%. You will also need a PTFE tube just under 1 meter long and possibly three extended screws.
