Hi folks,
I'm in need of the engine retaining ring for a Cox Sat 1B. I know I could rig something, but would love to have the proper piece. A great item to 3D print perhaps.

Also need an engine mount plate for an MPC Standard Arm. There are 3 offered that should have been in the kit: a standard plate (presumably for 18mm engines, a D engine mount plate, and an FX engine mounting plate.
Again, maybe a candidate for 3D printing?
I'd gladly take any of the 3 plates here if anyone had a spare. Of course, I'll pay cost and shipping.

Thanks in advance!

Allen
