PRUSA MMU2 Selector Improvements

prusaprinters

<p>These are some minor changes to parts of the Prusa MMU 2.0. Like many I had issues with keeping the cutter blade in place. To fix that, I added three pegs to the selector body and three matching holes in the blade holder. While I was doing that, I noticed that the blade was not as far into the notch as I would have liked. So I lowered the blade about .5 mm.</p> <p>As I was looking at the CAD model, <a href="https://www.thingiverse.com/thing:3080920">https://www.thingiverse.com/thing:3080920</a> I noticed that the filament path had some sharp corners. Chamfers and fillets were added in a few places. See the .pdf file for details.</p> <p>Update: I should note that while it is still a work in progress. These parts have been printed and they function as expected.</p> <h3>Print instructions</h3><p>Unassociated tags: prusa mmu2</p> <h3>Category: 3D Printer Parts Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2rqZ6Uo">i3 MK3</a></p> <p><strong>Supports:</strong> No</p> <p><strong>Notes:</strong></p> <p>Follow Prusa's original recommendations.
