Mechanical pencil support for BM2 erasers.

I made this to use the refill of my broken pencil

They can be bought all over the internet under the name BM2:

It works by rotating the cap which moves the eraser in and out.

I included the source file in case tolerances need to be adjusted for your printer/eraser.

There is also a folder in the src which includes removable supports to make the core easier to print
