<p>This is a remix of an item on Myminifactory created by Michal Fanta<br/> <a href="https://www.myminifactory.com/object/3d-print-filament-buffer-for-original-prusa-i3-multi-material-upgrade-85794">https://www.myminifactory.com/object/3d-print-filament-buffer-for-original-prusa-i3-multi-material-upgrade-85794</a></p> <p>I thought a printable buffer with easy access was a great idea. Michal did a great job with the design but the filament path was a bit ti tight and there where sharp turns on both ends that pinched the filament causing a lot of drag. I wanted this for my enclosed filament setup. The concept was to use Spanner hands spool holders "thing:2119644" then use ptfe tube to the buffer and again to the MMU2 unit on the printer. Thus slowing the absorption of moisture, prevent debris or dust, and keep things organized while allowing for access and easy routing.</p> <p>My version uses 8mm x 3mm neodymium magnets commonly found on amazon and M10 pass-through push fittings also found on amazon.</p> <p>Parts needed.<br/> qt:4 8mm x 3mm neodymium magnets<br/> qt:10 M10 Straight Pneumatic Push fittings<br/> qt:2 M3 x 15 screws</p> <p>Careful not to over tighten the M10 fittings as the printed thread will separate of you over do it. You just need to hold a PTFE tube not an elephant.</p> <p>Reccomend using PETG, ABS (compensate for shrinkage), or Modified PLA. for the frams. Standard PLA wont cut it here. You can use whatever you want for the dividers.</p> <h3>Print instructions</h3><p>Its going to be a long print. Make sure your printer is well tuned before printing this. Any flaws in the divider channels will ruin the print.</p> <p>Print frame in PETG<br/> Print dividers in PLA if you want</p>
