So way back in the day I found the Pokebox Switch case by 3D Printing World (https://www.thingiverse.com/thing:3474587) and I remixed the top of that case to be an Ultra Ball. The BEST Pokeball. More recently I found their version that same case, but it was hollowed out to hold cards! (https://thangs.com/designer/3dprintingworld/3d-model/Pokebox%20Card%20holder-28215) Since I'm a Commander player in Magic The Gathering, I needed a case that would hold at least 100 Dragon Sleeved cards and this one would not. To that end, I expanded the model pieces to fit my needs while keeping the glory that is the Ultra Ball from my previous remix. For now it is just the Ultra Ball version, but I will put the enlarged version of a ‘standard’ pokeball top in there as soon as I get the chance. The pieces that I have edited include everything but the Ring, Button, and Lid Catch.

Instructions:

Slicing done with Ultimaker Cura

I printed everything at .16 layer height because I wanted a finer end product for my deck box that required very little post processing

The Ultra Ball Insert, Ring, Catch, and Button were printed at 100% infill.

The Base, Lid, and top/bottom Lööps were printed at 5% Gyroid infill with 3 perimeters.

Supports were needed for the lööps and the button. The button could probably have been printed with no supports, but like I said I wanted very little post processing.

For the combined lööp and bottom, I used the same parameters as above!

Oh! And don't print the assembled model. Tis just for reference!

I added a combined loop that with a separate bottom that eliminates the gap from trying to glue the loops together. I had already combined the loops before I saw that How2Texan had pretty much the same thing for the version of this model that fits Switch game cards. I borrowed the bottom section that holds the button just to make life easier! Link to the inspiration below and I'll toss the whole thing into the remix section as well.
