8mm bearing mount

These were designed for my anet evolution custom after I started having issues with the bed frame I originally had on it. They are designed for 2 standard metal lm8uu or a single lm8luu bearing. I tried them with igus bushings but found if your tolerances weren't good enough you would need to upsize them to about 102% to allow for proper fit. This was used to replace the 2020 extrusion frame with a solid light weight piece of aluminum composite I had laying around in the shop.
