A redesign of the Prusa MK3 heatbed cable cover.
The heatbed cable is redirected sideways (see picture). This is ideal for cabinets. The printer takes up less space on the y-axis (approx 2cm) and the heatbed cable no longer bends against a cabinet back. It is 1mm taller than the stock cover, but does not interfere with the stock Prusa extruder/carriage.
Some resoldering will be involved.
v1.1 - made the cable channels and entry hole a little larger.
You will need:
- 3x M3 12mm screws
- 3x M3 nyloc nuts
Prepare the parts
- Check that the two parts snap together easily
- Drill out all the bridged holes with a 3mm drill bit
- Seat 3 nyloc nuts into the bottom part (if you have the solder heatbed version, just the center nut will do)
Place the bottom part
- Place the bottom part into position and route the thermistor cable in the channel
- Use a temporary center screw to hold the bottom part in place
Prepare the heatbed cables
- [See attached picture as a guide]
- Get rid of the stock O-crimps on the heatbed cable
- Shorten the red/VCC cable
- Strip the ends of the cable
- Curl the stripped end and solder the tip
- Place it the 'wrong' way (counterclockwise) around a screw and washer and screw down the terminals
- If you have the soldered heatbed version, simply shorten the red/VCC cable and resolder in the new position
Prepare the fabric cable cover
- Reassemble the fabric cable cover
- Complete the assembly
- Double check that you have not shorted the headbed terminals
- Unscrew the temporary center screw
- Place the top cover
- Ensure all wires are routed properly
- Clamp down on the fabric cable cover and push the cover into place
- Secure with the center screw
