I might have to revisit this, if not here's the file to print the faceplate on a smaller printer like the Ender 3. You'll have to split to objects and resemble the little nubs with this version because I neglected to separate them in to two different files.

I corrected the side the seam is on, I wasn't paying attention and centred it on the back instead of the front. Unfortunately for my wheel that means it's going to be offset and forever perturb me.
