A table lamp inspired by the tasty mushroom Morchella Esculenta.
It consists of two parts that are connected with a thread.
The parts where the light shines through the design (check images) are 1.6 mm thick.

What you need

A E27 (EU) or E26 (US) lamp socket kit that come with a screw-on attachment ring (check the images for a cross section with measurements). You can easily get the sockets with cord and switch on Amazon, Ikea or your local hardware store.
A LED bulb
Light-colored or transparent filament.

Enjoy your new lamp!

Important: You cannot use any other bulb type than LED! LEDs still give off a little heat. Depending on the strength of your bulb the design might warm up slightly. The material you use has a certain heat deflection temperature before deformation. Make sure to build a safe product by verifying that the print is not affected by the amount of heat that your bulb emits! If you are uncertain or have little experience in building electrified products, please consult a professional!
Usually, a strong LED bulb does not get hotter than 50 degrees Celsius while regular PLA does not deform under 58 degrees Celsius. Those are approximate numbers, and you need to verify that for own product selection.
