3d printed Pen holder

I made a new pen mount for the x-carve. Check it out http://www.thingiverse.com/thing:1543273.

Is that an open builds linear actuator holding the router? How do you like it over the stock one from Inventables?

That is a C beam from open builds but I only bought the rail and the carriage. The other parts to make it work are just modified x-carve z axis parts.

Is there a spring incorporated to ensure pressure on the paper?

When I have the marker cable tied to the Dewalt mount, it doesn’t always retain pressure.

I had a light spring on it. And it worked. But I found the weight to be enough on mine so I took the spring off.
