Ultimaker tape holder

A tape holder that can be snapped on the sides of the Ultimaker! Never have those tape rolls laying around the lab again!

**Update 10 Aug 2013**

- Updated the tape roll holder to version 2

- Added 3 different sizes. The sizes are actually 1mm wider than the file name tells you,
so it gives a little room for the tape roll. This also compensates for any plastic shrinkage.

- I have included the Autodesk Inventor file,
this should make it easy to modify if you want to!
