This is a half size version of my Catan Settlement/City/Road Storage box.
The design is not just a 50% scale of the design. The beveled sides of top and lid are the same size as is the thickness of the box. Direct scaling causes printing issues such as too tight of tolerances.
Sanding of the lid maybe necessary in order to open and close the box.
This box is perfect using my Catan Pieces (https://www.thingiverse.com/thing:2764066) scaled by 50%
