The JANSJÖ lamp is super handy, but it's also super directional—it creates a blinding spotlight that's difficult to use for reading or photography.

steubens7 created a diffuser that clips onto the bell of the lamp, but I found it a little bulky and fragile (couldn't keep the clips from breaking). So I took the concept and redesigned it for strength & a better fit.

NOTE: this design is tuned for the colored JANSJÖ. The black version of this lamp is a little bigger, so you may need to print at 105% to get it to fit nicely.
