Description

Prusa CORE One Swing Arm Cable/PTFE Brackets instead of the inelegant Velcro fasteners.

If you don't like the cable/PTFE management with Velcro fasteners on the swingarm, here is a more elegant solution using printable brackets (cable clamps).

Version Single for the cable and a single PTFE tube (standard CORE One) 

Version Dual for cable and double PTFE tubes in the case of an installed MMU3, but still has the standard tube to the side coil.

There is an improvement for the left swing arm bracket available (for noise reduction).

Instead the dual tubes for MMU3 and right side spool path a Y-splitter with E3D V6 collets or Bowden collets, designed for the brackets, can be used.

Printing recommendation:

Filament PETG, 0.4 Nozzle, 0.2mm Structural, 100% Infill, no supports

Mounting instructions: (see picture below)

  1. Starting at the pivot arm joint, slide the first swingarm bracket onto the arm with the cable facing forward, starting at the right edge and holding the arm from below.
  2. Slide the next swingarm bracket to the middle position of the arm, starting at the right edge and holding the arm from below.
  3. Slide the last swingarm bracket to the end position of the arm, starting at the right edge and holding the arm from below.                                                                                                                                          3a. Put the Nextruder cable into the brackets of the swing arm starting at the right side.
  4. Push the first past-swingarm bracket about 6 cm from the end of the swingarm, with the opening for the cable facing to the outside of the cable bend, onto the cable.
  5. Push the next past-swingarm bracket about 6 cm from the first bracket, with the opening for the cable facing to the outside of the cable bend, onto the cable.
  6. Push the last past-swingarm bracket about 6 cm from the middle bracket, with the opening for the cable facing to the outside of the cable bend, onto the cable.
  7. Now push the PTFE tube onto the brackets, starting at bracket 2
