Created for Starfinder starship combat, but I'm sure it could be scaled for use in other game systems.

Printed on my Anycubic Photon (original), default settings, flat on the plate, no supports, and they came out great.  Missile fins might be too small for most FDM printers, but I have not tried that myself.

Designed so they should nest when stacked, but I've only ever printed them flat on plate, and deformation of the bottom layers due to longer exposure times has always ruined this for me.
