Trade good / Commodity for Twilight Imperium 4th edition

I intended to upgrade my trade goods and noticed there were no models available except for on Etsy. I made a black/white design in photoshop and imported into 3D via Cura, and think the result is good enough - So I thought I might as well share the design.

The models are 20 mm and 30mm, halves are 1.5 mm thick. I'd suggest adjusting meassurements depending on what size you're looking for. Also, I included halves, since printing the full pieces could be a bit tricky.
