This is a remix of the V400 probe holder adding the T nut to fit the unique extrusions in this printer.
Remove the top extrusion cover to fit this. You might need to loosen the screws for that extrusion in order to make it fit.
This is a very tight fit so make sure your printer is dialed in and maybe use a negative Horizontal Expansion to help.
EDIT: Added V2 with an angle to avoid scraping the top cover.
The author remixed this model.
