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.
If possible print it in Nylon, as ProperPrinting does.
