I 3D scanned this Arrma part and edited the holes a bit so it's printable. It is a little bit rough on the surface.

The printed one is on the left. It fits without any problems, screw holes are a bit tight but it won't strip your screw thread as it's plastic.

If you print this using Overture Easy Nylon it will be pretty strong.

Example is printed in PETG.

It is a bit rough because it's 3D scanned.
