I liked the design that this was based on but had a few issues. I don't include unaltered parts here. Look back to the original design by vampyrex13

  • the mount didn't sit completely flat on the carriage plate. The lower idler rollers are mounted on a slightly enlarged hole. This caused the support base to not sit fully flat.
  • the fan duct was a bit too close to the bed in the front. I angled the duct down by 2 degrees
  • the top of the duct printed pretty thin, so I thickened it a bit both top and bottom
  • added strain relief for the cables.

There are now 3 supports.

  • one without the mounts
  • one with the original accelerometer mounting based on the original design
  • an updated one with mounting holes for anADXL343 accelerometer

I don't have accelerometer so the mountings are untried. I printed this version in case I want to try it later. The cable support allows you to insert the cables without disconnecting them. Just route through the slot. The nuts are press fit.

You'll need:

  • cable ties
  • 5 - 12mm 3M cap screws, 2 more using the accelerometer mount
  • 2 - 3M hex nuts, 2 more using the accelerometer mount
  • 1 - 2M hex nut to attach the fan to the duct in the upper left. You can use the original screw... no need to use the bottom 2 screws.
  • 2 - 2.5M nuts and cap screws for the adxl343if using

Note:

My initial print quality with the BIQU H2 was poor. I got in touch with the company and they recommended changing the retraction to 1mm and the retraction speed to 15mm/s. Both worked really well for me.

Filament:

Hatchbox PETG

Notes:

I printed this with 4 parameters for extra strength. The PETG so far has been working fine for the duct. It sits right up against the sock and shows no sign of distortion. Time will tell. If need be, I'll just print another if it deforms over time. I never use ABS and didn't want to bother trying to get ABS working.

**The Strain relief**does** need supports for printing.**
