Ant Test Tube Rack

Description A rack for keeping ant test-tube nests horizontally — the way founding colonies should be stored. Glass tubes (water held back by cotton) lie on their side in full-length cradles, with the closed ends backing the water reservoir so tubes can’t slide through. Lift the whole rack to move your colonies without disturbing them. Prints vertically, used horizontally. It’s modeled tubes-up so it prints without supports (45° collars at every joint), then it sits on its side in use so the tubes are horizontal. Built for ant keepers Holds founding test tubes side by side (fully adjustable) Open rim underneath leaves a **channel for a heat cable** to gently warm the tubes from below
