This grindstone is an old asset that I revamped recently with Substance Painter. 

It’s a rigged asset, however the rig is only designed for Blender. 

The mechanism of the pedal and wheel work together and it has just a single main control as you can see in the images.

though it’s just a simple system it has some little quirks about it for example sometimes the foot pedal’s rotation and location don’t immediately update with the wheel, but for a simple asset like this it’s not been an issue in the animations I’ve made, just something I wanted to make sure you’re aware of up front. 

The textures of the main file are the lower resolution versions, but also included are the higher resolution textures if you need them.

This model is designed for Blender, however everything but the Rig should be ready to use in other programs and I’ve made files like FBX, glb, obj, ect for convenience.
