That's so clever! Will be building it soon.

Thanks for this! I have printed with PLA and it is a bit loose. I am wondering if this is because of the 0.15mm reduced size. I am going to try to print in Nylon. Please would it be possible to have a couple of the original beam_pen.stl to try that instead?
Also, I wanted to ask what material did you print with for your model that is on the ev3dev website?

stewardj: I reduced the diameter of the cylinder from beam_pen.stl by 0.15 mm. Let me know if it is enough?

JackJ106: The building instructions + code will be available soon (1 or 2 days) on the project page: http://www.ev3dev.org/projects/2014/07/16/Drawing-Robot/

Hmm, I tried this print in PLA but the beam_pen2 pieces don't fit on the beam pen holder. They are just too snug. I tried printing with 1 shell and 2 shells with a similar result. Any chance you could resize one or the other? I'm hoping to print this for a class. Thanks!

Oh and can you send me the building directions for this and the code file?

You know if you change out the pen holder with a metal/ aluminum print head , add a print bed and a up access of the design this could be a fast and great 3d printer. O you also would need to change the code a little.
