Here are a few of our downloadable 3D models. All of them are CC0 so use them as you wish!
I'd be interested in what projects they end up.

I added a new downloadable Spear Trap! It is a demo item for a much detailed pack I'm currently working on. It will feature various realistic dungeon traps, disarming devices, such as switches, levers and more.

Nice work, and very cool of you to offer it for free :)

Thanks! I hope it will find a place somewhere in a dark dungeon, awaiting for silly adventurers! Heh-he :)

Another handful of downloadable models. This time, some weapons for fantastic heroes!

Feel free to use them in your projects! Credits are nice but not mandatory.

A tiny low-poly style Koi fish for you:
