Two models for 30mm memory spheres, One with symbols and one without on the handle, If anyone needs larger sizes I can edit, or you can simply upscale.

(edit) Upon testing it needs to be scaled down, maybe 10% until I fix it, the ball comes out the bottom.

I would recommend the supports under then handle. I tried both ways and this gave me the cleanest print.

Sand it smooth and give it some silver paint!
