PTFE Tube Mounting Mod for TwoTrees SK-1
In the stock setup, the PTFE tube runs through a hole in the printer’s frame and is held loosely by a rubber grommet. This printed block replaces the grommet and allows you to mount two PC4-M6 fittings on both sides of the aluminum profile, creating a solid and reliable connection.
✅ No more PTFE tube shifting inside the frame
✅ Clean and stable mounting
✅ Optional second PTFE tube connection (e.g. to a dryer or external spool)
✅ No drilling or frame modifications required
To complete this mod, you'll need two PC4-M6 pneumatic fittings
Print settings:
– Recommended layer height: 0.2 mm
Note:
There is a small dot on the printed block – this dot shows the correct orientation for mounting the part into the aluminum profile. One of the photos clearly shows how it should be positioned – use it as a reference during installation.
