After many failed prints of the original model, I finally managed to redesign the rocket and to get a great print of this toy. This model is quite big (from a Mosaic perspective) and looks fantastic :). You will have a lot of fun with this thing !

You do not need any infill or support structures. The model itself has a small raft on the bottom part which stabilizes the toy during the print.

The rocket is hollow. I plan to put a Multicolor LED inside. Let me see you rockets !
