These are a few additional pieces designed to work with Rocketship Game's hexagonal 'Deployable Containers' which are available on DriveThruRPG here: https://www.drivethrurpg.com/product/216929/Deployable-Cargo-3D-Printable-SciFi-Containers
The joiner is a simple hexagonal ring designed to let you glue two printed, open-ended containers end-to-end. It's slightly undersized so scale it when you print. 102% works for me, but you may have to experiment.
There are also two open 'cage' style end variants, one with a snap-in moveable door, and the other a fixed cage. Combine these with the open ended container to transport your 28mm dangerous lifeforms or prisoners.
There's a half hexagonal 'support' stand. This lets you stack a set of these containers horizontally in a 'beehive' style formation.
I'm a hobbyist war-gamer based in New Zealand. I'm focused on creating original 3D designs for 28mm scale war-gaming that can print quickly and easily on low priced hobbyist consumer 3D printers.
