UPDATE: I've re-uploaded the bottom LH adapter, it was not showing the cutout for the wheel.
These solve 2 problems with the KE and SE printers, the vibration on the Z axis due to minimal connection to the plastic base and plate below. This solution also allows for adjustment of the angle to try to get this as close as possible to 90° to the bed
THE VIDEO WILL BE RELEASED ON SATURDAY MORNING
Very little hardware is required for this upgrade, as long as you've already done the previous 10 heat-set inserts from the previous video/upgrade, which can be found here https://makerworld.com/en/models/373923#profileId-281622

10 pcs M3 x 5mm Heat Set Inserts (Into Arms)

I've used PETG CF - I'd recommend anything stiff for this job, I don't recommend using PLA if you plan on printing inside of an enclosure. ABS, PC or other similar materials, PETG-CF works well since it is quite stiff.
These need to be printed heavy, please use glue stick on these, some areas have smaller contact with the BP.
I'd use 8 walls and 20% infill, Gyroid is good or Cubic, I'd also thicken the infill.
ENJOY!
