CNC Pen

This little springloaded pen fits nicely in the 43mm router adapter on your CNC. Replace your Kress router motor with it, on plot away.

It is designed around a 3.2mm ball pen refill. There's a spring for hight compensation (around 13mm diameter). Easy to print, easy to assemble, easy to plot.
