created this design to mount a BIQU SKR 1.1 board to my AM8 / 2020 / 2040 printer.
it should also fit the MKS GEN-L and the newly released SKR 1.3 board
hole distance = 101.85 x 76.10mm
if you are currently planning your build I can highly recommend to give the very silent TMC2208 stepper drivers a try!
mount the board with 4pcs M3x16mm screws and M3 nuts.
extrusion mounting holes are 6mm wide and 5mm deep for M5 screws (x8 or x10mm)
