On my hat, the 3 pin is too big and the 4 pin is too small so I invented a gadget that can give me a 3.5 pin. It's a little change, but it's a life changer.

Warning!

I made this design for a hat from the classics and it says yupoong below. After some testing it doesn't work for all hats. If anyone knows anything about standardized hat sizing and if there are some kinds of big brands I can make it for, I am happy to make more. If not, it's only 2 grams and 12 minutes so it might be worth a shot.

I am quick to respond and would love to help any of you!  Almost all of my work is inspired from helping a friend or family member make something that hasn't before existed. I hope you enjoyed and if you did you should check out some of my other stuff.
