This is a question about fodpereiraAn adaptation of the modified version of the Poké Ball Easter Egg. I added an Easter pattern while keeping all other components unchanged. Here are their printing and assembly instructions. I followed these instructions, and the result was excellent:

Assembly instructions:

Print all parts and clean them if necessary
Insert the button into the button body hole
Stick the button assembly to the central ring with the groove facing upwards
Insert the bottom into the central ring
Align the hinges of the top and center rings and snap them into place
Done! Now let's go catch Pokémon!

The hinges should be lightly polished to prevent them from becoming "stuck". At first, the hinges may be quite tight, so please slowly adjust them to their full range of motion!
