I have made this model to get very close in size and looks to the original Light Soy lamp by heliograf, it is based on the great Design by TumTomor.
I have increased the Size of the Fish Itself & changed its proportions to fit, in total the Lamp with base is around 35cm tall.
You can either hang the lamp or print the stand and use it as a desk or nightstand-lamp.
To be able to print the fish itself it is split in 2 parts right where the threads start. (Seam not visible behind the cap)
*VERY IMPORTANT: To get as close to the original size as possible the Fish without thread is 26.9cm tall, therefore not printable with a regular MK4/MK3S+ (I have printed it with an Ender 3 S1 Pro)!

For anyone who wants to print it with a MK4/MK3S+ i have added the Version
LightSoy_Fish_Prusa_Z_Height_VaseMode.stl
which is 21cm tall, but obviously looking a bit more bulbous.
*EDIT (24.08.2023):
For those who want to print the full size version with a smaller z-height printer, I have split the fish itself again. It is split just above the sign and below the scales to not interfere with the texture too much. To avoid having a dark band across the fish, it does not have a inset brim like the threads do, so it will probably be a bit finicky to glue the whole thing together.

Printing Instructions:
To act as a translucent Lampshade i have printed these Components in VASEMODE or Spiralize Outer Contour(Cura). To get stronger prints in Vasemode you should increase the line-thickness; I have printed 0.8mm thickness with a 0.2mm nozzle (In my experience this is the max. you can get away with), You can increase the temperature by 5-10°C to get better prints and should slow it down to around 75% of your normal printing speed. (Depending on how good your part cooling is). Depending on your bed adhesion i would recommend a rather wide brim especially when printing the tall fish.
I have printed the Cap with 30% infill, no supports although you could probably get away with way less infill too.
The stand was printed with 50% infill to get some weight, so the whole lamp does'nt get to top heavy.

Assembly Instructions:
As a Lightsource the Cap fits E14 Sockets & most slim LED Lightbulbs, i have use the following:

(Note; with this one you would have to take the wire out of the socket, put it through the cap and then reconnect it again)

(Note; Good for Desklamp, for Nightstand to bright)
