The minimum size is one and you would need to turn off center supports, for the othere sizes, need to watch out for screw hole lining up with the center supports.



noticed during printing supports walls don't join up to the back plate. version 2 has been uploaded to hopefuly fix the problem.

sorry for the quick changes but when i made one for smaller tools they didn't sit nicely so version 3 has option for a tool guide.
