I had to make even cylindrical obstacles for ant experiments and decided to try out laser cutting test tubes into small chunks.
If i got on a lower power setting and keep going around and around, it will actually cleanly cut through, but i got bored and opted for a technique of just etching the glass with the laser, and using its built up heat to bring it under a cold tap water and the two parts just pop off rather cleanly.
I'll be adding fluon to these so the ants don't crawl up and into them.
