A true sine wave profile lamp shade. Since some people have a Prusa Mini, I modified my lamp shade to make a mini version [176x175x175] of the original Sine Wave Lamp Shade [243x196x198]: https://www.prusaprinters.org/print/41599/edit.
Ideas to Use:
Goes with the full lamp assembly: https://www.prusaprinters.org/prints/41234-curvy-lamp-shade-with-stem-assembly
Print with the max layer height [0.25mm on the Prusa Mini] with 1 perimeter and 0% infill. These settings are defined in the .3mf file.
I recommend printing with Prusament White PLA for the best translucency. An off-brand white PLA may or may not do the trick even with only 1 perimeter.
