I made a SpaceX starship model out of 6mm MDF for my 3 year old son.
It snaps together no glue needed, just need to manually cut a little bit of MDF after Assembly of the Starship and the heavy booster so they will fit together.
I also spray painted them, the booster is all silver and starship is half silver half black. Sorry for my very quick and dirty paint job.
I also etched lines on the pieces witch look nice. There are only 3 grid fin instead of 4 couldn’t find a way to fit it but it looks nice with 3.
