Emisar D18 Optic Ring

This is a simple re-creation of the stock optic spacer ring in the Emisar D18 flashlight. It's not an upgrade in any way, just allows you to make it the color of your choosing.

The part is 0.84mm thick, the stock one is 0.80 as I measured. 7 layers at 0.12mm layer height works perfectly. Recommend printing with concentric infill. The space between holes is 0.60mm, so you may have to get creative with your outlines. I'm using a .30mm nozzle and I printed it at 105% flow.

Unscrew the bezel and remove the glass and stock spacer, the small clear o-ring beneath the glass can be tricky to get back in right. Be sure to keep your printed spacer from warping or curling up or it will be extremely hard to get everything aligned right.
