Cetus Pen Holder

Here is a pen holder for your Cetus printer. It allows you to insert a pen and use your 3d printer as a 2d plotter. This is the first part that I have designed and printed myself.

Use screws similar to those provided with the cetus to mount to the extruder assembly. Alternatively give these a try for the main clamp.
