Functional Pokéball - Nintendo Switch Game Cartridge Case

I wanted a cool way to hold my switch game carts and this is what I thought to do.
I modeled this pokéball a couple of months ago and it's one of my first big 3D printing projects; I'm quite proud of it and hope you all can enjoy it too. With the new Pokémon Let's Go games being announced I figured it's a great time to share!

Design
---------
There's already quite a few nice pokéball designs on Thingiverse (see https://www.thingiverse.com/thing:1615753 by MrFozzie, https://www.thingiverse.com/thing:411193 by Intentional3D, & more), but none were exactly what I wanted. So I figured I'd improve my 3D modeling skills while making exactly what I want.

I made this in AutoDesk 123D Design, which is apparently discontinued now. I was going to share my design files until I heard that. However if you want the files to make any edits feel free to message me.

The pokéball can open and close (you can even add a small torsion spring to the hinge so it pops open). When printed at 100% size, you can use 1.75 mm filament as the hinge (I actually permanently melted the filament into the case using an old soldering iron). The button also has a spring in it and feels really nice. I used pen springs for the button and hinge (cut it and bent the ends), though you may be able to find nicer ones.

I made a few different layouts, but only…
