This is a pen tool for drawing with pens up to 13mm in diameter. It does not have any active components, which means the machine's Z axis can be adjusted to "lift" and "lower" the pen. This tool has a built in laser cut flexure, allowing you to increase the pen tip pressure by increasing the push distance slightly, for about 2mm total travel.

Laser Cut Parts

All Laser Cut Parts should be cut from 3.175mm (0.125in.) Delrin. If you are certain that your laser cutter applies automatic kerf compensation (rare), cut the original DXFs. Otherwise, cut the offset DXFs. (If you are uncertain, cut the offset DXFs.)
