This simple printed part allows a Pilot G2 pen to be attached to the printer so 2d pictures can be plotted on a piece of paper.
The part is threaded to fit a pilot G2 pen. When inserted upside down the pen benefits from the spring allowing constant pressure on the paper even if the bed isn’t perfectly level. Since the part is threaded, you can adjust the pen’s pressure simply by turning the pen top.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
