This shows the complete assembled terrarium/formicarium. I've slightly modified the bottom parts to have 15mm space under it to use heat mats for the type of ants I'm going to keep in it.
While it certainly is quite a lot of screws this serves very well if you're paranoid about security. In this version, no silicone was used to tighten it even further as the Camponotus spec. is way too large to utilize any <1mm openings that might occur.
