There are six options to choose from:

• umb_ptfe_wire_ziptie.stl has spots for an umbilical cable, PTFE tubing, and a music/spring wire.
  • umb_ptfe_wire.stl same as above with no ziptie.
• umb_ptfe_ziptie.stl has spots for an umbilical cable and PTFE tubing (also picture on my printer).
  • umb_ptfe.stl same as above with no ziptie.
• umb_wire_ziptie.stl has spots for an umbilical cable and music/spring wire.
  • umb_wire.stl same as above with no ziptie.

Umbilical clip is sized at 6mm diameter, which fits the LDO Nitehawk cable nicely, but will likely work for other CANBUS or USB toolhead cables. The clip may be secured to the umbilical cable with a zip-tie, but if it clips on and doesn't slip then a zip-tie is not required.

Music/spring steel wire hole is sized at 1.5mm, which fit my 1mm wire well. PTFE guide is 4.3mm for 4mm OD PTFE tubing. If any slight adjustments need to be made, please leave a comment and let me know, and I can make those updates. STEP files are also included in this model if you'd like to remix it yourself.
