Big Flaky Rocket

This model of the Tintin Moon rocket is a remix of Pierre Muth's work (which was inspired by Gregory Vienot's version). The rocket shape comes from the Pierre's dxf file, I "ported" it to OpenScad (with minor differences) using this splines library to be able to work with it as I wanted.

The goal of this version is to provide a lightweight assembly based on individual tiles to be able to print it at a large scale using as little material as possible. The provided STL files are for a 50cm version weighting about 130g.

The design is made of a thin shell of twice the 0.4mm line width plus the legs which can be printed with a single perimeter and no infill, and the parts just clip with each other with hooks and notches, which have a fixed profile dimension independently of the scale. The OpenScad source file should be used to set the scale parameter, re-scaling the STL files is not advised.

The picture looks somewhat particular with the auto-resizing, luckily there is a "View Original" button to see it at the correct ratio ;-). The green one is the 50cm print, the medium red one an earlier version, and the tiny one is Pierre's design printed at scale 1 (I'm impressed how small this design could be printed and assembled, with some minor post-processing).
