Prints great on a 0.4mm nozzle. 

Note: this DOES have a seam in the original design. 
Don't forget to use cornstarch to prevent clay from sticking to the roller! 

UPDATE: 11/13/25:

I've added a seamless roller version.  Note: I have not printed it myself.  I haven't had the need to, but I've had a few people request for it since the original has a seam in the design.  I am NOT a Blender expert, far far from it.  But hopefully someone likes/appreciates the seamless version.
