Really love this mount by jblonski. It called for M3 x 30mm bolts for the cap on the bottom, but I found these to be almost impossible to find unless you order them online. Had to settle for #4 - 1-1/4" bolts instead... although I hate using imperial stuff on my all metric shapeoko 2. But, they fit nicely. All in all, a really great model. Thanks for sharing!
