Da Vinci Extruder Clip-on Calibration tool

Calibration tool that you can click on the Da Vinci Pro 1.0 extruder.

First i printed an other calibration tools (http://www.thingiverse.com/thing:718768) but i thought it wasn't correct enough. So I designed this one that will click on you're extruder. Once its on you can slide you're dial indicator in (if the hole is big enough). The hole on the .stl-file is 8mm!

1. Print the .stl file
2. Remove the support
3. Drill the hole so you're dial indicator will fit (the hole on the .stl-file
