This easy helicopter sand mold is designed in Fusion360.
The model should be easy to print. Print it with organic supports at least for tail. The thickness of perimeter walls is 1,2mm so 3 layers with 0,4mm nozzle or 2 layers with 0,6mm.
I will print it myself once I got back from vacation but I hope that I will see some nice prints in comments before!
The author marked this model as their own original creation.
