4 Way Tube Crossing

thingiverse

This is a custom Tube crossing for 13mm tubes that I use for my ant colony project. The top section is intentionally left open to provide ventilation, and you can easily add some mesh material and weld it in place using a soldering iron set to around 250 degrees Celsius. In fact, this is exactly what I did myself. No additional support is required as I utilized the Brim feature for added adhesion during printing.
