Nhẫn Dương Vật Công Thái Học v3

(Edit 1/22/25: There was a problem with the larger sizes all being the same size that was kindly brought up to me.  I have fixed it now, though I think now they won't exactly correspond to the previous file dimensions)

I have taken what I have learned from playing with designs so far and created a new ergonomic ring.  I had uploaded this before and took it down because I was unhappy with the egg shaped cross section which I found to be more uncomfortable with a tighter fit.  

• The primal type ring is comfy to wear all the time, but thinner rings can get a bit less comfortable to wear when put into action, unless they are not tight enough.  This ring is a bit thicker and has a very comfortable rounded inner diameter.  I might go thicker still, but it would need a bit more work.
• The ergonomic shape which sweeps back towards the taint is quite nice and doesn't push the balls forward during use.
• This design uses a squared cross section versus circular.  I had previously uploaded with an egg shape design but this hit pressure points with a tighter ring which I believe I have corrected this time.
• This design again has a locator triangle to ensure it is oriented correctly (point goes on the top towards you).
• Again I have generated a large number of sizes in mm denoted by the file's last two digits.  These sizes run about the same as what you would want for a round ring.
• Prints without supports.

Everybody has their preferences, so maybe you'll like this one.  I will probably keep experimenting because I am having a blast.
