These diffuser and shader caps are designed to reduce and direct light from ceiling mounted MR16, GU5.3 LED bulbs - perfect if your bulbs are too bright or scatter too much light. A great solution for balancing light levels without replacing your bulbs.
Originally created to tame slightly overpowered bulbs, these snap-fit accessories redirect or soften the beam as needed.
Included 4 models:
Diffuser (0.4mm, no hole) – provides light diffusion, white/transparent PETG recommended
Shader (0.4mm, 10mm hole) – open for central beam and shades on edges, black PETG recommended
Shader (0.4mm, 15mm hole) – open for central beam and shades on edges, black PETG recommended
Shader (0.4mm, 20mm hole) – open for central beam and shades on edges, black PETG recommended
You can adjust thickness in your slicer to fine-tune the brightness and diffusion to your taste.
It is recommended to use housing metal spring to keep bulb and diffuser secure inside.
Print & Material Notes:
Tested with PETG (recommended over PLA for heat resistance)

Print on smooth PEI for less diffusion or textured PEI for more
You may also consider to use Transparent PETG for diffuser purpose if you want to avoid light intensity decrease even slightly

Happy printing—enjoy the perfect glow!
