Ok, I am making this new LIMITED EDITION design tonight (see cad drawing). Everything else will be identical to the one I posted last night (pictured below). 1.23″ Stainless Steel over Bronze with a 1/8″ ceramic ball. Spin times over 5 minutes. $75 plus $4 for domestic and $8 for international shipping.
I will take orders until 3:30 today central standard time which is 3 hours from now. At that point I will not take anymore orders and will retire this design! I can make either rotation spiral so let me know. Respond to this post if you want one. Paypal payment preferred. These will ship on Monday! Let me know if you have any questions.
Edit: Please let me know the spiral direction you want. The cad drawing is from the top looking down. We will call that standard and if you want it the other way tell me reverse.
It is recessed for grip
Here is the reversed drawing
