I like Exerqtor's concept, but I wanted a simplified version. The functional changes are to not use the UM2 style connector and instead have an opening that has a 50 mm radius to avoid pinching the tube, and no bearing.
Note that the guide arm is installed on top of the support/pivot. This reduces the amount of support required to print the support/pivot and the top face is smoother. Use a M5 button head screw to secure the arm with a lock nut on the bottom and washers between everything.
Update - the original guide arm holds the PTFE tube too low, so I designed a modified guide arm that holds the tube higher.
I printed it with organic supports from the build plate only.
After installing the piece and reworking my PTFE tube I am really happy with it. The UM2 connector causes the tube to get pinched when bent to the side, while this design guides the tube to avoid pinching it.
The author remixed this model.
Simplified the pass-through to a single piece, changed to use just a M5 bolt, and the arm needs to be mounted upside down
