This is a model made for HicWic's Universal Mount for the MPCNC. I used his base Mini Mount and modified it until it would hold my Brother Vinyl cutter to my liking. It is very stable and will not budge when fully inserted. I have no tried to cut Vinyl with it yet, but I imagine that any failure would be due to something other than this part.
