Engineering my own design and borrowing elements from OntologicalShock's model (https://www.thingiverse.com/thing:2071698), these squad bases are made to fit the grid used on the map tiles of Star Wars Imperial Assault. Photos above are of painted prints.

Each base is a press fit for the game's miniatures and can be easily removed and reused to fit your needs. I highly recommend printing at least two sets and painting the pips with bright colors, ideally to match the game's provided tokens. No special prep or supports required. Enjoy!
