Description

PDF

I wanted to have my filament spools next to my printers instead on top, to reduce swinging of the filament spools and make my printers fit into smaller spaces. 

They use both ID2 OD3 PTFE tubes for guiding the filament to the extruder assembly.

 

I have designed two models, one for the MK4 and the other for the MK2.5 BEAR. Compatibility with other models is not confirmed (yet at least).

 

Both can be used with my BB Filament Spool Holder without problems. (See my other 3D models)

If possible, send pictures and feedback of your makes so I can modify the PTFE holders to be better!

 

PTFE tube holder for MK4

  • Uses one M3 screw that is 10-18mm long.
  • Can be directly swapped with the original bearing holder without extremely difficult disassembly.
  • Designed for use with ID2 OD3 PTFE tube.
  • PTFE Tube holder for the nextruder can also be found in my other 3D models. (Remix of other model)
  • Printed in two parts for durability.

PTFE tube holder for MK2.5 BEAR

  • One longer M3 screw needed (Around 18-20mm long)
  • Attached using the lower bearing holder screw (The mentioned longer screw) and the tensioner screws.
  • No actual disassembly required. Only three screws need to be removed for the part to be screwed on.
  • Designed for use with ID2 OD3 PTFE tube. (In the picture I have an adapter for OD3 to OD4 PTFE tube.
  • Printed in one part.
