Designed for the Koh-I-Noor Rapidomatic .5mm Mechanical Pencil. Protects the tip of the pencil and keeps it from poking holes in pockets.

I strongly suggest using a .2mm nozzle and printing at a very low layer height to allow the layers time to cool and improve tolerances. The model has been slightly scaled up to account for filament shrinking, if it is fitting loosely try printing at 93.1% scale (true to exact dimensions of the pencil) and go from there.
