Push-fit Bowden Hotend by rrhb Dec 21, 2012


This is a hotend cable coupler that is compatible with the listed push-fit adapter. It can be adapted to other hot end adapters.

I use this on my Openbeam Rostock (Kossel).

The default hole spacing is compatible with groovemount.

If you're using these push-fit connectors, the attached SCAD and STL will work as is:


Adjust couplingdiam for other push-fit adapters. If you tell me which one you use, I can generate STLs for them if you'd like.

The default hole spacing is compatible with the Makergear Groovemount spacing. I use it on a Groovemount-compatible plate to hold my J-head hotend in.


  1. Adjust couplingdiam in SCAD if necessary and create STL file.
  2. Print.
  3. Ideally use tapping kit to tap threads into the main hole. If you don't have a tapping kit, it is possible to self-tap if you are careful.
  4. Mount with M3 bolts or similar sized SAE bolts.
