Be assured of a good fit! Our 3D printed Sizing Rings are the same dimensions as our heavy metal rings and will help confirm your size prior to investing in a lifetime accessory. The Sizing Guide is great help but, if you need a little extra assurance, these plastic versions are very useful! We print them with body safe PLA plastic which is biodegradable and compostable. Colors vary.
Less Than FREE – Each set of rings comes with a Discount Code worth $50! The code is valid for 45 days, can be used to buy any regularly priced metal c-ring (Tungsten Carbide or Stainless Steel) but cannot be combined with other offers or discount codes.
Expand The Base Set: Want to test a wider range? Once you add a set of Sizing Rings to your cart, include additional rings and we’ll ship them all together!
Free Shipping: No cost USPS First Class shipping to U.S. addresses. International shipping is discounted, see prices during checkout.
Free Download: If you would like to print rings yourself or with the help of a 3D printing service, download the printable 3D models.
Get A Single Ring at Checkout: You also have the option to add a single Sizing Ring to any c-ring order during checkout. This will allow you to verify your ordered size before unsealing the high value ring, see our Returns Policy.
