I really liked the unibody style of riser and so I printed AP's remix of a K1 riser, but I found the distance between the corners was a bit too big resulting in the legs not fitting into the four corners of the printer.

This has a filament sensor relocation mounting point and glass slider rails.

Changes:

Reduced each side's plates overall distance

Reduced each side's beams overall distance

Added a hole in the rear plate for a USB cable passthrough (for LED strip)

Remove the 3rd knub in on each plate so there is no manual removal required after printing

Optimized print orientation of all parts and minimal supports for strength and easy printing

Colorized “Creality” text on front plate for multicolor printing

I also added the filament sensor cable bracket from here into the 3mf since it nicely holds the wire away from the rear belts after relocating the sensor. https://www.**********.com/model/905360-k1-max-filament-sensor-wire-bracket

Assembly is straight forward but here's a summary:

Glue and clamp the corners to beams

Glue and clamp the plates to their other half

Glue the combined plate assemblies into the corner/beam assembly

Done

Assembled plates and frame with LED strip in place.

Next step is to insert the plates and glue all together.

I used this LED strip: https://www.amazon.ca/dp/B0C2P6Y9QN

I used Bambu PLA, PETG or tougher would likely be better to mitigate warping.

I've since added the CFS to my K1 Max and it does not require the filament sensor anymore. I used the relocation mounting mount to screw the PTFE coupler from the K1 CFS Upgrade Kit and ran the PTFE tube through the same hole in the riser still. So this still works great for the K1 Max with CFS upgrade kit.
