D&D Calthrops Tiletoppers for OpenLock / Openforge

These are a handy way to represent calthrops when using Openforge or Openlock for D&D terrain. They are designed to be easy to use; simply put them down over your OpenLock or Openforge tiles, the lip underneath will stop them sliding around, and then remove them when you're done.

There are 4 files in this thing;

• a 1 inch square cut stone tile with 20 calthrops on
• a 1 inch square dungeon stone tile with 20 calthrops on
• a tiletopper base - this gets glued to the underside of the tile, and the lip on it is designed to lock lightly onto the underlying terrain so it doesn't slide around
• a single larger calthrop. Not strictly part of the thing, but I created it during the development process, and it might be useful to someone !

I used 20 calthrops on the tiletops, because it's what the Dungeons & Dragons Players Handbook states the "standard" item contains.

It is fair to warn you that on an FDM printer, this thing is also a complete torture test for stringing - either a good way to find out how well dialled in your printer is, or a bit of a pain in terms of post-printing clean-up !
