This lampshade needs to be printed in vase mode (spiralized outer contour in Cura)

The bottom layer/portion of the lamp will therefore be a solid piece (I couldn't figure out how to leave a hole in it when printing in vase mode) so you will need to manually cut-out the whole to fit the bulb fitting.

Once you have cut the whole, you can simply wedge the shade between the fitting parts.

The whole at the top of the lamp shade is wide enough to get your hands in to screw in the fitting and the light bulb.

The positive in doing so is that this will work with any size fitting as you can cut out the hole as needed (I used a compass protractor and an exacto knife to cut the hole).

Printed with:

• 0.2mm layer height
• Vase mode (spiralized contours)
• PLA+
