PTFE Filament Guide for the Original Prusa i3 MK2

prusaprinters

<p>I wanted a better spool holder for my Prusa i3 MK2, so I made one - you can see it in the photo and the files and instructions are <a href="https://www.printables.com/model/210176">here</a>. The new position of the spool required a better solution for guiding the filament to the extruder. This is a tweak of a printed part downloaded straight from Prusa 3D themselves which adds an endpoint for a regular PTFE Bowden tube at the top of the printer frame, above the PSU.</p><h3>Post-Printing</h3><p><strong>Vitamins</strong></p><p>You'll need approximately 60cm of regular PTFE Bowden tube (4mm OD, 2mm ID).</p><p><strong>Tools</strong></p><p>You'll also need a 2.5mm Allen key to take off the original part and replace it with this new design.</p><p><strong>Assembly</strong></p><ol><li>Remove the original part. It's the top bracket, holding the Z-axis linear rod in place, on your right side while looking at the screen of the printer. Save the screws.</li></ol>
