Big Flaky Rocket

thingiverse

This model of the Tintin Moon rocket is a reworking of [Pierre Muth's work](https://pierremuth.wordpress.com/2018/09/08/destination-moon/) (which was inspired by [Gregory Vienot's version](http://blog.gregory-vienot.fr/fusee-tintin-objectif-lune/)). The rocket shape comes from Pierre's dxf file, I "ported" it to OpenScad with minor adjustments using the [splines library](https://www.thingiverse.com/thing:1208001) so that I could work with it as needed. The goal of this version is to offer a lightweight assembly made up of individual tiles to enable printing at large scale while using as little material as possible. The provided STL files are for a 50cm version weighing about 130g. This design consists of a thin shell twice the width of a 0.4mm line plus legs that can be printed with a single perimeter and no infill, and the parts just clip together with hooks and notches that have a fixed profile dimension regardless of scale. The OpenScad source file should be used to set the scale parameter; re-scaling STL files is not recommended. The picture appears somewhat unusual when auto-resized, but fortunately there's a "View Original" button to see it at its correct ratio. The green one is the 50cm print, the medium red one is an earlier version, and the tiny one is Pierre's design printed at scale 1 - I'm impressed by how small this design could be printed and assembled with some minor post-processing.
