Quick swap base ( from ProperPrinting ) to MGN12H_mount

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3866258.

I remixed because I like the swap system ProperPrinting made. I adapted it for the BLV mod where the X-axis is based on the MGN12H rails. It happens to be the system I'm building... . I hope others can make benefit out of the swapsystem too now. The remix is only the base. You can get the lever at the original project. On my Anet AM8 I found the lever printed at 102% works best.

Enjoy.
