I've upgraded my Z axis using the same design in the build below. The only thing I can't figure out, it how to attach the router holder to the Z axis assembly. The holes line up to use 2 of the openbuilds 90 degree angles on the top OR bottom, but not both. Any ideas/suggestions on how he may have attached it? I don't see the 90 degree angles on his machine. Builder hasn't been online in a few weeks either. Thanks! https://openbuilds.com/builds/beefed-up-and-customized-ox-build.3163/
