Love it! It might be easier to cut from a blank, but I do like this 3d idea.
The bridge I used on the RC4A was a bit thicker and a lot heavier than the MM style bridge it came with (which went on the PB4 Frankenbass). As the RC4A is a fixed neck I was caught short on shimming it, and had to lower the bridge into the body about 2mm to get the action correct, but it came out nicely. The pics are in the link below, it looks much like this bridge, but not exactly the same.
