Giá đỡ ống PTFE cho máy in BambuLab

PTFE Tube Guide with a Custom Base 

Improved version available: https://makerworld.com/models/1448989

• Main purpose: prevents the tube from hitting the top glass.

• Advantages of this model:

  • A lot more stability thanks to reworked base.
  • Added grooves hold the tube securely, which prevents it from bending too much or not enough (radius of about 38,125mm).

• Print recommendations:

  • Scale to 102% for ABS (to compensate for shrinkage) - or use included .3mf file
  • Supports needed (only for the arm) - printing it vertically upside down seems to be the most optimal way.

• Assembly notes:

  1. Remove supports and sand the seam on the connecting piece.
  2. Assemble the two pieces together (requires quite a bit of force).
  3. Push the tube through the guide.
  4. Connect the tube to the extruder.
  5. Slide this assembly down to the place of the original base and screw it in.

• Tested with BambuLab ABS, scaled to 102%, supports enabled, overhang cooling set to 100%. Cost: 4,3g (1,72m). Time: 36min59s (without calibration time). Fits perfectly. Assembled using quite a bit of force.
