MAKE SURE TO PRINT AT 0.2 LAYER HEIGHT OTHERWISE IT WON'T BE ACCURATE

Use this to get pin heights from a tubular key. Red Team Tools sells this now, which is pretty cool.

Here's how to use it:

Then use this to model your own key: https://www.thingiverse.com/thing:2802287

The heights are from the OpenSCAD file, rounded for 0.2 layer height:

1 = 0.4

2 = 0.8

3 = 1.2

4 = 1.6

5 = 2.0

6 = 2.4

7 = 2.8

8 = 3.2
