I printed two of these marshmello uncut keycaps with my MPSMV2 FDM printer. I printed this inverted 180 degrees with the top on my buildplate. My printer nozzle is 0.4. The stem fit is snug and fits like factory keycaps. I test fitted on Gateron, NewGiant, and Outemu switch stems. Painted with acrylic black paint.
