This remix is something I wanted for my Voron 2.4's exhaust cover on my toolchanger upgrades. The intention is to make the wiring a little nicer with just the canbus routed down the back left 2020 extrusion internally.  

Fusion 360, step and 3mf provided.

Revisions History

  1. 5x lines with PC4-M10 fittings; 4mm cable passthrough
  2. 5x lines with ECAS fittings; 6.3mm cable passthrough; 2.1mm piano wire holder (15-17mm deep); also added 2020 extrusion locating pins on the base module as quality of life improvement; preventing T-nuts slipping under the top component.

Design intention

  • Compact/Minimal front-visible cable
  • Voron 2.4 aesthetic - with inspiration from Friction's Voron Exhaust Cover (https://mods.vorondesign.com/details/sChDLllFG34KYroxSym6MQ)
  • Multiple bowden PTFE feeds - slightly offset for a toolchanger

Installation Example

My current install is a Voron 2.4 Tapchanger with 2 dragon burner toolheads and cartographer probe connected on T0 with EBB36 boards. The toolhead requires only the canbus and reverse Bowden tube.

BOM

  • 3x M3 4mm Heatset
  • 3x M3 16mm SHCS
  • 4x M5 8mm BHCS
  • 4x M5 t-nuts
  • 1-5x PC4-M10 pneumatic fitting for bowden connection [V1]
  • 1-5x PC4-M10 pneumatic fitting [OPTIONAL for back - V1]
  • 1-5x ECAS pneumatic fitting for Bowden [V2]
  • 1-5x ECAS pneumatic fitting [OPTIONAL for back - V2]

Installation and Assembly

  1. Insert the 3 heatsinks in the pcb mount piece
  2. Mount the PCB mount piece with 2x M5 bolts and M5 t-nuts to the 2020 but take care to locate it with the hole of the back panel. I'd also suggest dry-fitting the BTT CEB when you locate it to ensure you can slot the board!
  3. Slot in the BTT CEB into the pcb mount piece and secure with 3x 16mm SHCS
  4. Snap fit the pcb cover over the pcb
  5. Drill out the required bowden channel (I used a 5mm drill bit) in the Bowden and cable holder. These are printed intact to improve print quality.
  6. Screw in the PC4-M10 pneumatic fitting for the required number of channels or ECAS if using V2
  7. Feed the canbus cables through the channels
  8. Secure the Bowden and cable holder to the 2020 extrusion with with 2x M5 bolts and M5 t-nuts
  9. Insert your bowden tube
