A Hot End Bowden adapter

thingiverse

For Rostock printers, try Jamesarm97's Bowden clamp derivative featuring a threaded hot end top. It requires no mounting bolt tangs and has been rescaled for this specific hot end type. A big thanks to the original designer! Another option is a bowden tube mount on Thingiverse. To install, print the cap, insert the bowden tube through the cap's hole, and wrap PTFE or other tape around the tube end (about 2-3mm) for a snug fit when the cap is installed. Be sure to place the cap first before wrapping tape on the tubing. Wrap it about five to six times, then cut in half if needed. Position the tube and securely screw on the cap - you may hear plastic fibers cracking, but that's normal. Test for security by tugging the tube, and proceed with printing. Note: I recently built this setup, but the printer is not yet operational; your results may vary. The compression method uses an added collet from jamesarm97, which might need drilling to fit correctly.
