A modular cube formicarium.
The cubes can magnetize together for expansion and the inserts can be customized. I've included a blank insert to make it easy to design your own, but there are 2 pre-designed inserts for those who like them. The nest is large enough for my Camponotus pennsylvanicus, but even larger queens may have trouble fitting through the adapters.
The cubes can be hydrated via syringe or pipette from several locations. I use jumbo cotton balls as hydration medium.
The caps fit flush and can be gently removed using a flat head screw driver. The caps block off unused portals of the nest, but also fit the air line tubing I use.
The adapters I've included are for 1/2 outer diameter air line and 20mm test tubes. I've included links for the exact products I used.
This design has been a labor of love, but it is far from perfect. I encourage people to make new adapters, insert designs, and technical changes. Perhaps a larger model? Or a hole in the body for a hydration test tube? Go wild, but please include attribution as per the license.
Minimal supports are required for the adapters and caps, but should be easy to remove.
The Main body and inserts do not require supports, but I recommend them in order to get smoother holes.
The Back plate does not require supports.
The caps may need light touch up to insure they fit smoothly. They should be slightly snug, but shouldn't require force to put in place. Lightly sand if the fit seems to tight, you don't want to jam them in place. I recommend test fitting without the insert in place, that way you can push them out from the inside if they do get stuck.
Any clear and firm material should be fine for the front. The cubes are 2 inches x 2 inches which should make it easy to measure out something. I used acrylic cut from high quality card protectors, but you can probably find nicer pre-cut materials.
The magnets used are 6mm wide and 2mm deep.

The test tubes are 20mm x 150mm glass tubes. I use them for queen rearing.
