Clip-On Filament Guide for Prusa MK3S & MK3S+ w/ Rotating Head

prusaprinters

<p>This filament guide uses a 608 Bearing (22mm OD x 8mm ID x 7mm Deep) to allow the filament guide head to spin freely. &nbsp;Like most things I design - it is over-engineered. &nbsp;I just needed a simple guide to prevent tangling and 20 versions later - I had this. &nbsp;I wasn't initially planning on sharing it because there are many excellent filament guides on Printables already. &nbsp;However, it was so fun to assemble with the bearing, and it works so well that I had to share it!</p><p>I am not great at printing PETG and my mechanical parts (Nuts/Bolts) never fit together well with PETG, so I designed this clip to be made with PLA. &nbsp;Once printed, slide the bearing in the side and push in until it stops; &nbsp;It should be a snug fit. &nbsp;Feed the screw through the bearing and thread on the head. &nbsp;There is a tiny slot in the screw to tighten (lightly).</p><p>Please Share your makes! &nbsp;I love seeing the materials people use and their clever applications!</p><p>&nbsp;</p><p>**PLEASE NOTE: &nbsp;This design requires a 608 bearing for assembly! &nbsp;<a href="https://www.printables.com/model/154655-bearing-608">There are people on printables.com that have 3D printable ones</a>, but I have not tested them. This was designed using a store-bought skateboard bearing.</p>
