I just installed my Z-Plus and designed/printed this adapter the day I installed it. It’s a single piece 3D print with stainless nut and screws and no mods to the Z-Plus (no holes or anything). I will upload the file to GrabCad today.
Sorry, had to add a recess for the 8mm nuts on for the front screws. They were hard to stop from turning when I was tightening them down. Will upload the step files in a few minutes
