Small coffin

Important edit September 2019: I wanted to improve the design a bit, so I remade it from scratch in order to fix a few things that annoyed me about my first design. Some measurements are off by tenths of a millimetre though so parts designated as v3 are NOT compatible with the older bits.

Since my other thing Slug-like Tentacle (http://www.thingiverse.com/thing:1686256) seems quite popular, I've decided to upload my tiny coffin that goes really well with that one in order to create something that really makes people go "Ommygodwhatthehellisthat?!"

The coffin was originally an accuracy test that I made so you might need to do a bit of filing to get the lid to snap into place.
