Twist Formicarium Modules

Demo:

Here's a new connection method I'm working on for formicarium modules. These modules will be 3/4 to 1 turn screw on to connect modules. There will be a nub at the top of the screw to align and lock the modules when screwed together.

3/8" OD flex tubing should also just fit directly into the female Twist connectors. Connect modules using the 3/8" OD flex tubing or use the Twist male to male adapter.
See pictures.

I recommend printing test tube adapters with a flexible filament such as TPU. I have broken several test tubes using rigid filaments.

Included are adapters for compatibility with "Many Formicarium" connectors. https://www.thingiverse.com/thing:2377968

Test tube adapters are still being designed and tested. 12mm tubes tested. Test prints are being done with PLA. The fitment of the connectors may not be the same with different plastic combinations.
