To announce the arrival of our son and astronaut, Guus (Gus for English speakers), I created a little card that doubles as a rocket construction kit.
We 3D printed 60 kits (on my Makerbot Replicator 1) to send to our friends. A little card with instructions was slotted into the kit itself.
Share a picture of your rocket if you make one!!
This design should be printable on any extrusion type printer, simply print... and build!
