Modifying the original Pokeball-style Pokemon card box by @tonyk, this version of the holder incorporates a snap-fit mechanism for the lid, featuring detent-style locks to help hold the lid in place.
There is two notches on the cap and matching indentations on the centre piece, ensuring the lid remains securely in place. Simply press the centre button inwards to release the latch.
The centre piece of this model requires supports.
Came out great when printed with Bambu PLA at 0.2mm on my X1C with standard settings. The fit is initially tight by design but it becomes perfect with use. If you want, pull the cap on off 5-6 times and it should be sweet.
