MK3 Reverse Bowden

thingiverse

The Bowden hose is an effective solution for eliminating layering artifacts caused by filament extrusions and retractions on your spool. Even with a high-quality spool holder, some force is still exerted onto the extruder assembly, resulting in small imperfections in layer heights. By relocating these actions to the area between the tube end and the spool, you can minimize layering artifacts and achieve more consistent prints. To implement this solution, you'll need to purchase a PTFE tube kit from Amazon or use parts you already have on hand.

You only require a couple of feet of PTFE tube, but purchasing a longer length ensures you have excess material and high-quality fittings.
