This MTA Boomerang (Maximum Time Aloft) has been made with the templates and informations available on this site: https://matleteck.jimdo.com/mta/modelisation/ , warm thanks to its owner Matth who's sharing it. The Boomerang is pretty long so feel free to scale it 1:90.
If the demand is great, I will definitely cut it in two parts so you can print it at original scale and next be glued together.
You can adjust the infill of the boomerang itself if you want more rigidity or more mass.

VERY IMPORTANT: USE SUPPORTS
Enjoy throwing it!
