5 Wheel Buffer for MMU2
prusaprinters
<p>An alternate solution to MMU2S buffer. Easy to locate away from filament and easy to load.</p> <p>Somewhat of a remix (or at least inspired by) <a href="https://www.thingiverse.com/thing:3529934">https://www.thingiverse.com/thing:3529934</a> from jgillick</p> <p>EDIT: Loop the filament around the wheel twice before feeding to MMU2.</p> <h3>Print instructions</h3><p>Print everything flat. 1 base, 5 sets of verticals, 5 wheels.</p> <p>Insert a 508 bearing into each wheel. Assemble using M3 screws.</p> <p>Use 4mm OD PTFE to the MMU2 as well as out to the filament.</p> <p>I use a piece of double-sided tape (3M command tape/tabs) to hold it to the tabletop.</p> <p>I printed in PETG, but PLA should be fine. Used .4mm nozzle. Printed base at .2mm for quality/clearance for PTFE tubes. Verticals and wheels don't really matter on layer height.</p>
