The angry game markers are designed for use on 1 inch = 5 feet scale battle mats used in TTRPG combat. The size range matched the WOTC D&D size format:
1 inch - medium creature/construct
2 inch - large creature/construct
3 inch - huge creature/construct
4 inch - gargantuan creature/construct
The genesis of this design is that I do like using creature models for the combat sessions, but some models have delicate features prone to breaking if not handled with care. These models can be thrown in a sack and transported without much concern for breaking.
Images show the 1 , 2, and 3 inch printed models.
The author marked this model as their own original creation.
