Filament Buffer Plate - Enhanced and Printable
prusaprinters
<p>The MMU2S does not include a printable plate for the filament buffer.</p> <p>I have several brittle filaments that were almost impossible to load without breaking. The only technique that worked was fingering them all the way between the buffer and MMU. I found it quite difficult to push filament from the buffer to the MMU.</p> <h3>Solution</h3> <p>After moving to <a href="https://www.prusaprinters.org/prints/3044-wall-mount-solution-for-mmu2s">my wall mount solution</a> and seeing the buffer in action I could see no reason why a slightly smaller version wouldn't work just as well.<br/> <img alt="Buffer size comparison" src="https://cdn.thingiverse.com/renders/b6/fd/8e/a0/58/c174882e16fe53b486d4d47ca7c405b5_preview_featured.jpg"/><br/> I was desperate for more fingering room so I made a version of the plate that is printable on the MK3.</p> <h3>Enhancement</h3> <ul> <li>The rounded edge matches the motion used in pushing the filament to the MMU</li> <li>The extra room make it much easier to grab filament with the finger tips and push it further with each push.<br/> <img alt="Extra fingering room and rounded corners" src="https://cdn.thingiverse.com/renders/03/c9/ef/42/9d/5a904c12194fc12ba27061d31b2bba49_preview_featured.jpg"/></li> </ul> <h3>Honeycombed Plate</h3> <p>The honeycomb makes the filament coil visible on the top layer. Filament tends to travel through the holes when loading which isn't a problem on the first layer but all of the other plates need to be solid. <img alt="Visible filament coil" src="https://cdn.thingiverse.com/renders/27/b9/ff/a2/a8/e36cdd2af435a2c3644f6168ce437f78_preview_featured.JPG"/></p> <h3>Print instructions</h3><p>1x <em>s-buffer-plate_Honeycomb_245x210</em><br/> 5x <em>s-buffer-plate_245x210</em></p> <p><strong>Printer Settings -></strong> Original Prusa i3 MK3S MMU2S Single</p> <p><strong>Print Settings -></strong> 0.20mm - Quality MK3<br/> <strong>Rafts:</strong> No<br/> <strong>Supports:</strong> No<br/> <strong>Skirt Loops:</strong> 0<br/> <strong>Brim width:</strong> 0</p> <p><strong>Filament Type -></strong> Generic PET<br/> <strong>First Layer:</strong> 232<br/> <strong>Other Layers:</strong> 236</p>
