POSCA pen holder (up to PC-8K / 25mm dia.)

thingiverse

drop-in pen holder for pens with a diameter up to 25mm. I use it for POSCA pens... additional angle settings (as the 8mm chisel tip e.g. needs a 9° angle) this is a work in progress...the bottom part that holds the pen in place still needs some refinement to get the chisel tip perfectly horizontal...
