CNC Pen Holder

This pen holder enables you to write, draw or simply set markers with your CNC router.
The pen holder has a clamping surface of ø 20 mm. If you have a Stepcraft CNC machine, it can easily be clamped with a ø 43 mm -> ø 20 mm adapter.
Thanks to the rubber bands, it creates a consistently good typeface.

This tool is suitable for "BIC" ball pens (https://www.amazon.it/Cristal-Original-Confezione-Colori-Assortiti/dp/B002FKPY1S) and coloured pens (https://www.amazon.it/BIC-829009-384180-Pennarello-Lavabile/dp/B001ANX5IU).

I will consider any request for pen holders of different diameter ;-)
