The adapter is suitable for a large halogen bulb downlight that has been discontinued. The adapter is divided into two parts and can be easily assembled without the need for adhesives.

By elevating the LED bulb, diffuse lighting can be achieved through a glass cover made of transparent consumables. It is recommended to use white or light-colored consumables for printing in the upper part to optimize the light refraction effect.

It is recommended to use PETG material, and set the layer height to 0.20mm to avoid parts deformation in the future.
