After creating some more complex designs, I've created a simple VESA 100x100 mount for the ZimaBoard and a VESA 200x200 mount which also supports 100mm mounting.
The VESA100-200 mount is too big to print on my Prusa Mini+.
The ZimaBoard is attached using the original M3 bolts, so long as the bottom 2 perspex layers are removed. Longer M3 bolts are required if you wish to keep the original backplate attached.
The VESA plate can be attached to suitable mounting using M4 bolts.
Printing in PLA or PETG should be fine. I opted for PETG as the ZimaBoard and the back of a monitor can get a bit warm and didn't want to risk it warping.
