<h2>Meet the Smoothy!</h2>The Smoothy is a PTFE Bowden Tube Y Connector designed for smooth filament transport without catching or binding. This allows you to use an external spool with your Bambu Lab machine without disconnecting your PTFE Bowden Tubes.&nbsp;PTFE tubes are inserted deep into the connector for less wear on the FDM material. This allows for silky smooth operation.&nbsp;As the filament progresses towards the output, it passes through a precisely-designed taper that mates perfectly with the output bowden tube.&nbsp;All PTFE tubes must be inserted until each “stop” is reached (see cutaway diagram).&nbsp;Connectors must be the black type (not blue). The black connectors allow the PTFE tube to “pass thru” which is required for the design to work smoothly: <a target="_blank" href="https://www.amazon.com/gp/product/B0B97RWKQR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1" rel="nofollow noopener">https://www.amazon.com/gp/product/B0B97RWKQR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1</a>&nbsp;<h2>BENEFITS:</h2><ul><li>No Supports</li><li>No Overhangs</li><li>No Brims</li><li>Optimized Geometry</li><li>Designed for FDM Printing</li><li>Smooth Operation</li><li>Supports both PC4-M6 and PC4-M10 “pass thru“ connectors</li><li>Free to Download!</li></ul><h2>UPDATES:</h2><ul><li>The Smoothy Mount is now available! Download here: <a target="_blank" href="https://makerworld.com/en/models/18190" rel="nofollow noopener">https://makerworld.com/en/models/18190</a> The mount is not required, but available to those who prefer to attach the Smoothy to their machines. Without the mount, it can simply rest in-line.</li><li>Both PC4-M6 and PC4-M10 connectors are now supported.</li></ul><h2>TIPS:</h2><ul><li>Make sure ALL bowden tubes are FULLY inserted until each one reaches its stop point. See cutaway diagram for an illustration.</li><li>The output tube does not insert as deep as the input tubes.</li><li>After inserting each tube, you can rotate the tubes back and forth while pressing inward slightly to make sure they&#39;re seated squarely and fully.</li><li>Glue Stick is recommended.</li><li>PTFE tubes must be cut squarely at the tip (no angled tips).</li><li>All PC4 connectors must be installed for a completed design with smooth operation.</li><li>Tested with a 0.4mm Nozzle and 0.2mm Layer Height.</li><li>Print vertically with wide dual-port side on the bed.</li><li>PC4 connectors typically have tapered threads. As such, make sure you don&#39;t over-tighten them as they can create a “wedge effect” and can cause damage.</li></ul><h2>NOTES:</h2><ul><li>These work well printed in PLA. More durable materials can be used, but it may require clearance adjustments.</li><li>I’m currently using this for my Bambu Lab X1C with an AMS, which utilizes an external spool.</li><li>This is the first model that I&#39;m sharing, I hope you enjoy it!</li><li>The Smoothy can be used commercially, but can&#39;t be resold.</li></ul>
