MicroSwiss Direct Drive Cable Guide

Update Dec. 16, 2022: added .step files

Summary

This cable guide secures your wires on your Microswiss Direct Drive. There's also a cable guide for the X Gantry (where the original extruder went). These ensure that your wiring doesn't get damaged from movement.

This should be compatible with any fan duct setup, since this mounts to the motor.

This was designed for heat set inserts, but you can use M3 nuts, instead.

Parts Needed

• 2 M3x15 Bolts
• 2 M3 heat-set inserts OR 2 M3 nuts
• 2 small-medium zip ties

Instructions

Extruder Cable Guide

1. Print the Top Clamp and Bottom Clamp laying flat. 
   • No supports are needed
   • I recommend a heat-resistant plastic, such as PETG, or ABS. PLA may get too hot and become soft.
2. Insert two M3 heat-set inserts into the holes. See the photos. 
   • OR use two nuts in the next step.
3. Place the bottom and top clamp around the extruder motor and bolt it down with two M3 bolts. See the photos.
4. Place your wires in the guide and secure with two zip-ties.

X-Gantry Cable Guide

1. Print the X Gantry Cable Plate flat, no supports are necessary. 
2. Insert at least two M3 nuts into the top recesses.
   • There are recesses for 4 nuts, but 2-3 is sufficient. 
3. Bolt the plate down with M3 bolts (from the bottom).
4. Secure the wiring with two zip-ties.

Notes

I designed this to have a +0.2mm tolerance around the extruder motor. This should be sufficient for most printers, while still being secure.

The cable guide is designed for a wire bundle of about 15mm in diameter. If your wire bundle is thinner, you can wrap it with some tape.

The fan duct I'm using was made by @Calini:
