Da Vinci bed rail mount

I created this due to the bed bushings going bad on my Da Vinci 1.0A. The rods are 10mm and machined down to 8mm on the ends to fit the factory mount. I don't believe these are hardened rods. As far as I'm aware of they used this same mount for the bed rods on all of the bigger printers.

The machining down to 8mm on the ends make them hard to replace. I made this almost exact other than having the inside diameter of 10mm on my mount but then I wanted to include a m3 nut for the upper mount s
