Modular ant farm Formicarium test tube modification

Karl132's Original Model

Original test tube connectors were designed for a 12mm test tube, so I tried my hand at altering it to hold a 16mm tube. Currently untested, will be printing soon to see if it works out or needs any additional changes to hold a 16mm tube securely.

Latest Update:

08/05/24 - Added in a Work in Progress test tube to tubing adapter. Currently has an opening that tapers down from approx. 7.52mm to 7.4mm. 

Also threw in a matching support to hold the far end of the tubes level with the other end.

06/26/24 - Slightly increased diameter of opening, and length of upper reinforcement to better fit the 16mm Test tubes i have on hand, can add slightly larger or smaller if requested.

Original model designed for use with 12mm Test tubes, I've widened the opening to accommodate 16mm test tubes.
