Generic, serialized markers for tabletop gaming

This is a set of entity markers for tabletop, grid-based gaming. Each one has embossed numerals on the side as well as counted pips around the bottom, and they stack together like traffic cones for convenient storage. Thirteen distinct markers are numbered 0-12, and smaller accessory "hats" can add an additional distinguishing feature to some of the tokens. A vaguely skull-like carrying case is also provided (these will be baddies in my combats).

EDIT 2018-08-31: Revised cones to have better definition and less distortion on the numbers. Separated out the 'hat' piece into a separate file--print 6 of them if you want it all to fit properly in the caddy.

The cones have a 1mm minimum wall thickness and the case has a 1.8mm minimum wall thickness. (These settings work well for me using 0.5mm and 1.0mm extrusion widths respectively in Slic3r).
