Tks for the update, the cast parts look good.
What resin are you using, it would be visually interesting to cast it clear, the white parts look stylish.
If you plan to advertise your printer, black is the worse color (magazine editors don't like it, and even forbid it), white, and bright colors show off the product best.
If the resin is rubbery, you might need to add a filler (glass fibers) to the worm wheel to stiffen up the cast part.
Maybe a filler will help with the geometry issues too.
I've used glass micro spheres in epoxy, it makes it brittle.
For structural strength cotton flock is added to epoxy, I've seen it used on kit planes.
