Submarine Dolphin Badge

This is just a simple badge using Tinkercad tools, the purpose of this is to be given to people especially to get younger people interested in submarines. Those that are apart of the USSVI might be interested in this.
Now there is a few small steps for assembling the badge. Being a safety pin, and a hot glue gun. Once printed and cleaned up, put a decent size line of hot glue over the open space on the back for the safety pin. But before it cools, push the pin into place. Doing so will make a strong bond between the glue and pin in a way trapping it in place. once it cools down your good to go.
(Note in the pictures i didn't have ant metallic filament so to show it off nicely i just used some spray paint, this step can be skipped with said metallic filament)
Dimensions With: 3 1/2 Inch. Hight: Slightly over 1 Inch. Depth: 1/3 Inch.
Pin Size's (Do to how file names are i couldn't put the fractions in the names so here is a quick cheat sheet)
0.8 = 4/5 Inch Safety pin.
1 = 1 Inch Safety pin.
1.5 = 1 1/2 Inch Safety pin.
1.8 = 1. 4/5 Inch Safety pin.
Finally if you found this enjoyable, or are part of the USSVI. I would ask that you might want to check out the kit card i made that is also in the same group of submarines. thanks for your time have a great day.
