Lampshade for Ikea Holmö or any standard E27 socket

A simple lampshade made for the Ikea Holmö or any E27 lamp base.

The base can be printed in a darker color for contrast. The main lamp shade needs to be printed in vase mode. Print the lampshade in a natural/translucent/white filament, preferably PETG/ABS/ASA. Print settings that I have used:

• Bottom layers - 4
• Top layers - 0
• Layer height - 0.3
• Outer wall width - 1mm (0.6mm nozzle. With 0.4, you can probably got up to 0.8mm)
• Spiralize/vase mode
