The Sounders came out with a new logo and most of the new merch isn't my favorite. So I put together this keychain. I've printed with a color change for the logo details, but you can do what you want.
Both of the sliced files attached include a color change. The sliced files are in PETG, since I throw my keys around, but you can slice in PLA if you're a little more gentle on your keys than I am.
The stock model is about 2.5 inches by 1.75 inches.
Edit - Added v2 with a bigger hole for keyrings.
The author marked this model as their own original creation.
