Overview

The RangeVault FlexBand is a fully parametric, 3D-printable ring designed for everyday carry (EDC). Whether you need a perfectly fitted wedding band, an ultra-light gym ring, or a durable alternative to metal rings, this design lets you create any size ring, including in-between sizes, with precise adjustments.

Custom Sizing – True Ring Sizes

This Fusion 360 file allows you to generate any ring size with just two parameters:

  • Ring_Size – Set your exact size, including half and quarter sizes.
  • Ring_Type (Men/Women) – Adjusts width/thickness proportionally.

Everything else, including thickness and width, automatically recalculates to maintain proper proportions.

The inner diameter will match real-world ring sizes, ensuring an accurate and comfortable fit.

Included STL Files

Includes several standard ring sizes as STL files for quick printing.

  • If your size is included, simply load the STL and print.
  • If your size is missing and you're unsure how to use the Fusion 360 file, just ask.

You can also use the provided project files as a guide for print settings. Just replace the STL with the size you want to print.

Print Settings

  • Material: TPU (95A recommended)
  • Print Speed: Slow (~20-30 mm/s) to ensure a smooth surface and prevent stringing.
  • Layer Height: 0.2 mm for 1st layer and 0.1 for the rest
  • Infill: 100%
  • Cooling: On, to avoid deformation.

Why Choose the RangeVault FlexBand?

  • Flexible and Comfortable – TPU ensures a snug but non-restrictive fit.
  • True-to-Size – Designed to match standard ring sizing.
  • Durable for EDC – Sweatproof, lightweight, and tough enough for everyday use.
  • No Metal, No Worries – Ideal for workouts, work,  shooting, or whatever.

This ring is part of the RangeVault EDC series, focused on functional, everyday carry gear that blends durability with practical design.
