Thanks. I went ahead and printed four of each, assuming I would replace them all. I don't currently need the cutouts of the lower belt mounts, but decided to go ahead and print them in case I adjust the size in the future.

Thanks for the design! They printed out nicely in black Hatchbox PLA. Once I get them on the machine, I'll post a make with photos.
