2020 / 2040 Filament Guide

prusaprinters

<p>When I upgraded my original Prusa to a Bear frame I mounted the spool holder on the top back of the frame. &nbsp;The filament dragged across the top bar which was sub-optimal. &nbsp;I created this guide to a) get a good angle off the spool and b) have a good angle into the extruder.</p><p>The guide has a print-in-place ball swivel through which you pass the filament. &nbsp;Probably &nbsp;totally unnecessary, but I hadn't every designed one before so I gave it a go. &nbsp;I do like the way it works.</p><p>The spool holder in the photos is from Thingiverse here: <a href="https://www.thingiverse.com/thing:4307007">Bearing Spool Holder remix for Bear MK3/MK3S 2040</a> and was designed by (Thingiverse user) <a href="https://www.thingiverse.com/iandouglas/designs">iandouglas</a>, who states “…Remix of <a href="https://www.thingiverse.com/thing:2809118">https://www.thingiverse.com/thing:2809118</a>…”</p>
