Arcadia Quest core box organizer - remix

This is a remix of https://www.thingiverse.com/thing:2268278 to improve the stability of all the elements in the box.
I used most of the parts of the original except:
- AQ_box_4_gold.stl
- AQ_box_5_sleeved-cards.stl

The new parts make it possible to:
- prevent the gold tokens from moving
- the corner is to be put in the corner (logical not?) of the trays to prevent all the elements from moving
- prevent the cards, figurines supports and their insert from moving

I used the hole for figurines supports of https://www.thingiverse.com/thing:3768723
