This is a generalized remix of my design of Rose’s Rebel Alliance iris ring from The Last Jedi. I wanted to make a hidden symbol iris ring that people can customize and put the symbol of their choice at the center.

I made an instructional video on how to customize and get the formatting right for the symbol of your choice:

So the STL files for a generic ring are included on this page, but you should look at the instructional video I made for Rose’s Rebel Alliance iris ring on how to print and assemble it:

The only uncommon material needed for this build is M1 x 6mm cheese head screws. I listed my source under in the .pdf (or .xlsx) BOM under “Thing Files”, but hopefully someone can find a better source.

STL quantities to print:
Iris Blade, Hidden Symbol Iris Ring {QTY 6x}
Symbol Insert, Hidden Symbol Iris Ring {QTY 1x}
Base, Hidden Symbol Iris Ring, XXmm ID {QTY 1x} [see below for different sizes]
Cap, Hidden Symbol Iris Ring {QTY 1x}
Slotted Disc, Hidden Symbol Iris Ring {QTY 1x}

For the Ring Base there are various sizes, to fit different finger sizes:
Base, Hidden Symbol Iris Ring, 13mm ID
Base, Hidden Symbol Iris Ring, 15mm ID
Base, Hidden Symbol Iris Ring, 17mm ID
Base, Hidden Symbol Iris Ring, 19mm ID
Base, Hidden Symbol Iris Ring, 21.6mm ID
Base, Hidden Symbol Iris Ring, 23mm ID
Base, Hidden Symbol Iris Ring, 25mm ID

The "XXmm ID" refers to the inner diameter of the ring portion being XXmm in diameter. This should allow you to pick the right size Ring Base for your needs.
