Straight forward print for an insert to turn a spare octagonal Pokemon tin into a deckbox - complete with a little drawer for status tokens and dice. This model specifically is meant to fit the slightly shorter octagonal tin, the kind that comes with 3 booster packs. It can fit a 60-card, single-sleeved deck. I have not tried fitting a double sleeved deck inside. I'm not entirely sure it would fit. The accessory drawer helps keep things vaguely organized while in transit, but is not strictly necessary.
The insert snaps into place on the rolled rim of the tin and stays put very well. But it is possible to remove it if necessary by CAREFULLY pinching or moving the tabs out of alignment.

I've printed several out of PETG, PLA, and PLA-pro and they've each worked well.

NO BRIMS OR SUPPORTS NECESSARY
