55mm 13 Pin Mechanical Steampunk Iris

thingiverse

We will update with a make. Long pins and extended bezel are designed specifically for a 2mm acrylic lens, which requires an additional cut in addition to printing. The pins attached to the fins lock into tracks within the nut, while press-through pins can be installed without glue, clicking past the outside of the bezel ring by 0.2mm. To assemble the parts, I recommend sliding each fin onto the track through the center of the nut, then placing the entire nut with all fins onto the bezel in its open position. With everything aligned, it should be possible to press each fin into place within the bezel. Minor sanding may be necessary. Soaking the bezel in boiling water for 30 seconds or so after the nut is fully assembled can help push the pins through.
