A popular modification to an Emisar D1 or D1K is to replace the stock reflector with a beutiful Ledil Olga TIR optic. However, it's a couple mm short of being a perfect fit. The pro fix is to increase the thickness of the PCB, but something simpler for most people is to add some o-rings to make up the face. This ring is designed to provide the necessary spacing and to center the optic.
Instructions:
- Print the ring out of a heat resistant material, such as ABS or BPET. It's a tiny print so it should be easy even if you have trouble with ABS. PETG might be OK too. PLA and HTPLA are not suitable.
- Place the bezel face down and press the ring down. The shelf side (the bottom when printing) will go under the optic when installed. It should fit snugly, but not be too hard to put on. You may have to adjust the size slightly depending on your printer and the material printed from.
- Remove the bezel from the light and carefully remove the stock reflector. Don't touch the interior of the glass and use a lens blower thing to remove any dust as necessary. Fingerprints will make you sad.
- Press the light carefully down on to the ring and optic. Again, it should be snug, but not too hard to fit.
- Screw the bezel and lens back on. It should apply a small amount of pressure on the optic to center it and hold it in place.
- Take a look at the beam pattern, to see if it's centered well enough and symmetrical.
I designed this with an OLGA-M in hand, which is moderately floody. Other versions are the same size and should fit, providing a throwier beam if desired, but they don't have the pretty faceting.
