xTool M1 Ultra - Fine Tip Sharpie Adapter

This adapter allows you to use your favorite Sharpie Fine Tip markers with the xTool M1 Ultra - note that the lid must be open and the appropriate custom pen settings need to be selected. We had success with 140 pressure and 81 speed, as a starting point. 

Tested on an A1 mini with Bambu Labs PETG HF. If you find the fit is too loose or too tight, I suggest adjusting the scaling in 0.1% increments for a perfect fit.
