Endmill holder/carrying case

This is a portable endmill carrying case for the Pumping Station One hackerspace in Chicago. It's purpose is so that the user can easily bring their personal endmills to the cold metals work area to work on the bridgeport mill. It adds quite a bit of convenience, since you no longer have to keep to tools in separate containers. It's roughly the size of a pack of crayons.

The holder itself can fit up to 3" long endmills. The purpose of the inserts is two-fold: 1) They position shorter endmills up higher, so they are equal length in the case, and 2) they stick out from the bottom, so if an endmill becomes wedged in the case, you can push it out.

Versions:
- V1.1: Added support for 1/4 x 2", 1/4 x 3", 3/8 x 2", 3/8 x 3", and 1/2 x 2.5" endmills
You just need to print the appropriate inserts for the various lengths. The most common sizes are still supported from V1.0.

- V1.0: Supports two 1/4" x 2.5" endmills, two 3/8" x 2.5" endmills, and a single 1/2" x 3" endmill.
