Surface Grinder Wheel Balancer

I needed a grinding wheel balancing jig for my Doall surface grinder. I was looking at machining and welding one up, but this is a much simpler way to make one and it works just as well. Please ignore the multi colors as I was using up the filament I had and figured it will be all black in a couple of months out in the shop anyways. Also before anyone says it, Yes that wheel is all used up. I just used it for designing.

The files for the actual grinding wheel are obviously for my model grinder, but i included them so that you can get an idea of how the wheel is mounted.

First the base gets printed and then i purchased these linear rail from amazon and cut them to fit.
