Alien Cow Farmer Puzzle V2

See https://youtu.be/13rdK3BD5A4 for description.

This is a slider puzzle that can be printed as separate pieces then assembled together. The Sandwich part can optionally be glued to the Enclosure part.

2021-03-29 EDIT - The first print had tolerances that were too tight to slide. This new version is larger and should assemble and slide together better. I can't figure out how to modify the STL files in the original upload, so this version is uploaded as a completely new project.
