Customizable Jellyfish keychain fidget toy

This jellyfish prints in place and has tentacles that slide down and up. No supports needed. The 3 tentacle size is the best size for a keychain.

This print is customizable and allows you to select the number of tentacles on the jellyfish (increases size); different eyes and mouth styles and whether to add a keyring hole.

Click on “Customize” to see all the combinations!

As a bonus, there are toggles to hide the shell and see how the collapsible mechanism works, and to see the tentacles expanded (don't print it like this).

Inspired by @zou3d designs and created from scratch using openscad.  

Notes:

• Sometimes, the middle tentacle can be a bit stuck right after printing. Applying a bit of force will easily snap the few points of contact it has with the other tentacles and make the mechanism start working.
• Printed this in PLA. Any infill percentage will do. I found it better to set the seam position to “Back”.
• If you want to add this to a keychain and don't have a clip-on. What I did was to pause the printing when the top of the ring hole wasn't closed, add the ring, and continue the print.
