Gramophone Spacer Ring

Hello all:

I needed a small (50.5 mm) spacer ring for my gramophone arm assembly , there was none available so I designed one myself. Note that this one is a first edition and may or may not be accurate for the holes but I made then a little wider and longer to give the part some play when you fit it on the neck of the arm assembly.

As my printer is down for a bit , I will be a day or two to get it right. First print can be a little out.
