Adapters for standard pen holders used in vintage plotters (Roland, HP, etc.) to hold Staedtler Triplus pens.

Separate files for standard 1.0 mm, 0.3 mm "fineliner"/ "superfine" (adds 1 mm clearance for longer pen) and mechanical pencil (accomodates slightly thicker body)

STEP files attached for editing.

Suggested additional print settings:

0.20mm SPEED works fine on Prusa CoreXY and MK3.9

Print with triangle cutout facing up or you will get supports on the inside, which will be annoying to take out.

You will need a brim!
