Instructions

Print as large as possible for the most FAB results.

If printing the model from separated parts:
The tail prints best with 0.1 layer height. If you prefer not to assemble the main body from two halves, a "main_body.stl" file is also provided. In any case, the intake vents on the main body will require support. Depending on your printer and slicer, the tail may or may not require support.

If printing the 'all-in-one' model (standing on its tail rockets):
April 3, 2018 Update: I've replaced the previously available "TB2-with support.stl" with a new version ("TB2-thicker+support+repair.stl") with three improvements.
1) All surfaces are now solid.
2) Thin surfaces on the tail section have been thickened.
3) Improved built-in support.
This is the recommended model to print (a minimum height of 125mm is recommended).

However, if you prefer a model without supports, another new version ("TB2-thickened2.stl") is also provided. Use supports when printing the new version, then paint as desired.

A third version ("TB2-repaired-needs_support.stl") is also provided. This model does not include the thickened tail surfaces and will only print correctly at sizes larger than 150mm high. It is just a repaired version of the original model by Tobs and, as the name suggest, requires supports enabled to print. This model should slice and print faster than the thickened versions.
