Projet Meduse

A ligh fixture based on an ESP32 and RGB adressable LEDs in the shape of a jellyfish

Status

Alfa version! Print this 3D models at your own risks. I have already fully printed and assembled a first prototype (small size) but there might still be some tweaks to make to the 3D models. Also documentation of slicing parameters, printing tips and assembly instructions is work in progress. If you have my contacts, message me on matrix or signal if you want to build a meduse light before the doc is finished

BOM

Come back later for the list of materials needed for this project. Or contact me to get some info and help me finish this doc ;-)

What to 3D print and how

You need to print 12x of one of these files :

• meduse-small-no-magnet.stl
• meduse-medium-no-magnet.stl
• meduse-large-no-magnet.stl

Small size if 150 mm dialeter jellyfish. Lage size is 300mm.

Then you have to glue these 12 parts together to get a full jellyfish body.

Alternatively, you can replace some pairs of parts with one of each of these

• meduse--bottom-magnets.stl
• meduse--top-magnets.stl If you want to to split the body in sectio,n that attach together with 5x3mm magnets.

For the first prototype I built I used 2 "bottom-magnets" and 2 "top-magnets" parts to split the body into 2 halves

If you want to put magnets everywhere and not use glue at all you'll have to generate the .stl file from the souce .scad. Check for the parameters at the top of the file to enable both top and bottom magnet pockets.

It is recommended to use clear PTEG filament to print this model. You can somehow have a translucent body with some non clear filaments but you'll have to use very low density infill (like 5%), only 2 layers of shell, and the result wont't be great anyway. (That is what I did for my firt prototype build, using white PETG, but I quickly ordered clear PETG when I saw how it looked. Check the firt prototype pictures in the doc directory)

Come back later for more slicing and printing tips. Or contact me to get some info and help me finish this doc ;-)

Assembly instructions

Come back later for this par of the doc. Or contact me to get some info and help me finish this doc ;-)

Model source code

The model is designed in OpenSCAD. The source file is meduse.scad

There are some parameters to select the model size and add optional pockets to fit small magnets If you make some improvements to the model or create an alternate version fell free to send me a patch by email to 12b at distrilab dot fr so that I merge it into this repository.

The files meduse-petite.scad meduse-petite..stl are not part of the project. You don't have to print this part to build the light, unless you want to torture test your 3D printer.
