Mini Tape Gun - Tape Dispenser

UPDATE* IF you are having trouble getting the printed teeth to cut, check out the remix section, some great solutions have been created to solve this. A mini tape gun for the Christmas elf in all of us. Print one of these and get to wrapping presents. This is a 3d printable version of a mini tape gun I had laying around. It holds the standard tape dispenser rolls. You know, the little 3/4" rolls that you use to wrap presents with at Christmas time. It prints in 4 parts with support and the little side piece that holds the roller on it simply pressed into place as the layer ridges seem to hold it in. But if that doesn't hold, a bit of super glue will fix it right up. Note: The screw threads are left handed because of the tape spool rotation direction. Update 12/29/2015: I've made some of the requested changes and uploaded the additional files.
