I have dreamed for long of a glowing mushroom lamp. After several iterations (and failed attempts) it is ready.
I wanted it as close as possible to a mushroom with a design that allow to print it easily. It is designed in Blender.
It consist of 3 parts:
1- the base allows it to be stable and to fix the socket. The smaller mushrooms are here for stability. They are quite thin so this part should be printed with 3 or 4 perimeters for them to be strong enough. It prints without support (some parts under the mushrooms are not perfect but you don't see them),
2-the foot is printed in spiral mode to improve speed and let the maximum of light go through. I used a brim (3mm) for better adhesion and it allows to maintain the hat better, so you should leave it.The only caveat is that spiral mode must finish horizontally, so you will have to cut it perpendicular to its direction. For that I used a dremel and masking tape to be sure the cut is straight and the layers don't separate,
3-the hat is optional, some people prefer it without, it the looks more like a flower. It should be printed with an angle like in the 3mf file provided: the layers are much less visible, the quality is better and (not obvious) it will need less support.
To mount it you need a E14 socket, a hollow screw that you cut at the correct size a nut some cable and switch, all easily available in a store.
You first screw the socket to the base, then pass the cable and connect it to the socket. You can the put the foot on the base (after cutting it). It has a more finished feeling if you glue it but it can be used without glue.
You can then mount the flame shaped led light bulb. Of course it is much nicer with a RGB one.
The hat is just putted on top of the foot and with the elasticity of the brim it should fit nicely.
Enjoy !
