Boli Bic plotter

thingiverse

Here is a small piece I made to match the Stasxp piece that converts your 3D printer into a drawing plotter in a very easy way https://www.thingiverse.com/thing:2417066 for Bic pens, which counteracts the unwanted movement of the tip. It's very simple, works with an M3 nut and an M3x10 or longer screw, and the usual elastic grommet. It's a very simple design but it works very well.
