Ant Nest Starter

As a ant keeper i need tons of nests. Sadly most of the time they are really expensive.Thats when i decided to make one myself. PLA is fine, but for optimal use PETG would be better for the water. Its a great ant nest for a colony of 20-100 ants.SMALL SIZED ANTS ONLY!!! the Biggest ants i have used it on are Messor Structors. Lasius nigers would fit too! The Tube size is 10mm, the tube hole is 9.8mm for a thight fit.I used a microscopic glass of 76mm * 25mm with WITH SHARP CORNERS
