After Searching for some mounts that would work with my Anycubic Kossel Mini I found a decent mount created by Guco back in 2015 and adjusted it slightly allowing for more mount options, as well as greater range of adjustment.

I wanted something simple but that would let me adjust at all 6 mount points of my MK3 220mm heated bed. Finding something that would give me good access to the mounting screws as well as the adjustment screws was a challenge just because of where the holes in the heat bed lined up. Borrowing Guco's original design I modified it slightly to work with the extra screws and nuts you would be left with.

• Made the mounting hole slightly larger to fit an M4 screws
• raised the inset for the adjustment nut to work with M3 x 15 or larger

This set up works great with my Anycubic Kossel allowing me to level the bed at all 6 points with good accuracy.
