Model rocket!
Goals
The goal of this project was to create a model rocket with all the features (shock cord mount, launch lug, ...) but without the hassle. The provided 3MF is ready to go to the printer - no supports or any other slicer adjustments needed.
How to print
While the rocket needs brims, they are already modelled in! so you shouldn't need to add one yourself. The modelled brim is connected to the object using small tabs, so it is very easy to remove after print.
You shouldn't need supports or any other modifications - print as is. I printed with the default 15% infill.
Assemble
For recovery, you'll need a parachute ($3 from hobby lobby; or make your own from a garbage bag), shock cord and of course the rocket engine.
On the bottom of the cone there's a notch to attach a parachute and shock cord. The rocket body has a hook on the inside for the shock cord.
The engine goes in the threaded side. once you place it you can screw on the engine cover.
Customize
Designed in FreeCAD 1.1, so may not work with earlier versions.
The FreeCAD file has these sections:
Master sketch - most of the measurements are here. Any edits or changes will likely happen here
Base parts - the rocket parts modelled based off of the sketch. some of edits happen here, mainly things that are perpendicular to the master sketch (like launch lug pad and pocket).
Print bed - the rocket parts above, but laid out correctly for printing and with a brim. If making edits, export these parts. Do not export the "print bed001" part. Do not edit these parts except for print related features (like brim).
