# Formicarium - Tube Expansion

This is a set of useful parts that I use when the size of the current formicarium is not sufficient anymore.

It is designed for 160mm x 16mm test tubes and tubing with 14mm outer diameter.

**Entrance**

The entrance part has open holes for the ants to enter or exit the expansion.
7 test tubes can be inserted for the ants to enter.

**Support**

This part is used to support the back of the test tubes so that they all stay aligned and level with the entrance.

**Spacer**

The spacer can be used to fixate the distance between entrance and support so that the 160mm test tubes do not become loose all of a sudden.

**Connectors**

A collection of tubing connectors compatible with 14mm outer diameter tubing and the entrance part.

**Terminators**

Two different terminators can be attached to tubing so that the way is closed. 

- a closed terminator
- a 2 part air terminator where you can put a mesh so that air flow is possible.

This is a new wider (66mm) Roller for the [Single Spool 4L Drybox](https://www.thingiverse.com/thing:4792927) to fit my filament roles.

The angles are slanted to the sides like [railway axles](https://www.youtube.com/watch?v=vkzgcJGdUnA) to keep the filament role self-centering.
