I have the Atomi brand smart light/sconce from Costco (Model Number: AT1680) and wanted to make something fun to prevent birds from perching on the top of the light and defecating on it…

Insert the need for a crystal themed topper!

This is printed in two pieces - the crystal base, and the ring holder. For both, I would recommend printing in PETG, ABS or ASA (especially if living in a warm environment). The PETG seems to be holding up well, despite getting up to 100 degrees F here. Please note that you will have to bend the ring base slightly to slip this over top of the crystal base - this is intentional.

Use a transparent filament for the crystals! Please see below for a very generalized guide for the settings/filament used:

Crystal Base:

• Filament: Inland PETG Transparent
• Nozzle = 0.6 mm (Recommended, but not entirely necessary. See tip below.)
• Max Volumetric Speed = 9 mm^3/s
• Infill = Gyroid at 7% infill
• Tip: The slower you can go, the more transparent the filament will be! The 0.6 mm nozzle also produced a much more transparent result with respect to the 0.4 mm nozzle. If you happen to have one lying around, definitely use it!

Ring Holder:

• Filament: Elegoo PETG Rapid - Black
• Nozzle = 0.4 mm
• Max Volumetric Speed = 9 mm^3/s
• Infill = 100% OR increase walls to fill the object

Included are both STL and STEP files! Happy printing, and enjoy the extra character added to the light!
