Here are a few designs that I've posted to Thingiverse lately:
The first design is the Cerkit Institute for the Advancement of Technology logo on an OpenLOCK "A" wall template.
Here's what it looks like after being printed:
The second one is a Cryo Chamber/Elevator Shaft for use in space or Steampunk themed adventures. I've since updated the model to include a fan duct on the top. This is compatible with Dragonlock and OpenLOCK terrain systems. It also has a baseless version to use with any terrain system or as scatter terrain.
