M10 Bowden Coupling

thingiverse

After I installed a Capricorn bowden tube in my Ender 2 Pro, the stock bowden couplings could no longer hold it reliably. Since many users reported positively about printed self-centering clutches, I also designed such for my Ender 2 Pro. A "normal" long coupling and a slightly longer one for the hotend because it has less space for the wrench on my printer. In case anyone is wondering what the white adhesive strips on the bowden tube are for - they indicate whether the bowden is moving in the couplings. Printed with PETG, line width 0.5 mm, layer height 0.1 mm. **Note:** This model has a tight fit. If you can't put the bowden through the hole, clean the hole with a drill, and if this still doesn't help, retract the walls of the parts by a few hundredths of a millimeter (in Cura with the "Horizontal Expansion" setting and in PrusaSlicer with "XY Size Compensation").
