About this 3D model

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/fTVNxSo5Evi Using the $20 GT2 upgrade parts from http://www.printrbot.com, I was able to combine the extensible X-axis mod and a GT2 mod so that I can print over the entire build plate with no X-axis slippage. I believe these parts are still printable on a stock, Printrbot Simple V2, if rotated and possibly printed without a skirt.
