Situation
The stock TVÄRHAND lamp leaves the bulb completely exposed, which looks great with a large, dim bulb. However, I wanted to use brighter smart bulbs. A diffuser was needed to soften the light and reduce glare when looking at the lamp directly.
Task
Create a shade that nests inside the existing metal frame without any modifications or adhesives and diffuses the light evenly.
Action

- Modeled a reference bulb to ensure clearance
- Designed the diffuser to friction fit into the lamp frame
- Printed in vase mode (one continuous spiral) using white PLA
- Placed one or two layers of tape around the neck of the diffuser to increase friction
Result
The diffuser slides perfectly into the frame, hides the bulb, and spreads light evenly without casting harsh shadows.
It went from a large dim bulb:
