I downloaded the Sienci motor covers and printed them out. These are great protection for the motors and the motor wiring that is exposed. I put the covers on but immediately noticed the covers seemed spongy when tightening down the 2 screws that hold the covers on. After removing a cover for examination it was obvious that the screws needed some support under the cover where they sit on the motor frame. I took a look at the 3D print file and decided to add pedestal extensions to the covers so the cover screws could be snugged up without having any spongy or wobbly cover movement.
As provided, the covers rely on their side ribs to keep the cover centered on the motor. By adding these pedestal extensions to the covers it provides a more solid mount for the cover as well as head room for the wiring to keep it from being compressed by the cover when snugging up the screws.
It takes about 3 hours at 50% print infill to print each cover. I have attached my 3D file for anyone who wants to give it a try.
I am using the Prusa slicer software for this project…
