Ultimate Spring Carpenters Pencil Holder

I modified the original to use it with a carpenters pencil about 15x7mm dimesion.
additionally you need the spring from the original design.

I recomment beveling the corners of the spring to make insertion easier, I managed to get down to few mm with my benchtop, the remains was done with a vise.
All the credit to Oscarko, I just did some .stl hacking.

In order for the .scad to work you need the original file at a certain location, but I am sure you'll figure that out.
