I successfully modified the part. I sharpened a brand new 1/4" wide chisel on the diamond hone we have for our kitchen knives, then shaved off some of the plastic at the top and bottom of each opening. I didn't get the pieces as even as I might have liked - some are more like a hump, higher in the center than at teh ends. If anyone else trys it, my advice is to not cut too deep on each pass, and to flip the chisel over, using the back of the blade to chear out the shavings at the ends. You have to make four cuts for each opening, one from somewhere in the middle in each direction on the top and bottom of each opening.

I understand that Larry will be re-doing his mold.
