Hex Base holds 2x 12mm dice with Slide-In Monster Stand

I'm brand new to 3D printing and tabletop gaming. Here's a base I designed for gloomhaven monsters that will hold 2x 12mm dice (HP, etc) and has a slotted groove to slide-in the monster standee.

I've been printing the monsters connected to the base, as I've yet to find a glue that holds as well.

I've printed 10-12 of the hex bases, some white, some gold, to then slide the monsters into during play.

Feedback welcome, will happily modify.
