Sistema anti torsione universale tubo PTFE per estrusori bowden (montaggio diretto hotend) V2.0

thingiverse

It has probably happened to someone that they've had trouble removing the PTFE tube from the hotend in the bowden system, sometimes even damaging the small PC-M10/6 insert irreparably. This is mainly due to wear on the same tube, which tends to rotate in the quick insert when the nozzle moves along the X-axis from right to left and vice versa. This problem worsens when you try to shorten the tube as much as possible because the distance between the extruder and hotend are the Achilles' heel of this system compared to direct drive. The problem logically reduces if we lengthen the tube significantly, but it compromises a lot on push and retraction filament tolerance. To overcome this problem, I thought of creating a joint on the tube with 360° crazy rotation using a simple MR105ZZ bearing and two quick PC-M6 inserts; the rest is all printed in simple PLA. This allows for free rotation of the PTFE tube without compromising its rigidity in push and retraction, and it will also allow us to work with correct lengths of PTFE without having to lengthen them too much. VERSION FOR DIRECT APPLICATION ON HOTEND, USEFUL ON VARIOUS MODELS THAT USE THE PTFE FUBO ATTACHMENT ADAPTERS PC-M10 WARNING This version is usable with a 37mm PTFE tube inserted into the hotend throat calculated for the Geeetech A10 hotend as reported in this project; adjust the length of the tube based on your printer model. https://www.thingiverse.com/thing:3752841 Video: https://youtu.be/4Rm1LEIUWuQ Materials: https://www.amazon.it/gp/product/B07X2WC7JW/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 https://www.amazon.it/gp/product/B01N53WD4R/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 WARNING: use a 37mm PTFE tube piece. https://www.thingiverse.com/thing:3752841 --------------------------------------------- Look at my project! https://www.thingiverse.com/thing:4623521 Follow me for more projects please;) https://www.thingiverse.com/duegi/designs YouTube channel: https://www.youtube.com/channel/UCjzOMzw1dpHyQkL1ib5DhQw DONATE / SUPPORT THE CHANNEL If you like the projects I've created and would like to support me, you can do so here.
