The 3D-printed (and hand-coloured) model measures 145mm (5.75 inches) in length. British spellings in honour.of the country of origin. Print as large as possible for the most FAB results. 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. Update: I've also uploaded "TB2-with support.stl", an all-in-one version with built-in support. This version prints very easily, with just a little painting required, as shown in the pictures here.
