| About me: | Hi there! I'm a 3D printing enthusiast with over a decade of hands-on experience, and my passion for this innovative technology hasn't waned a bit. My designs are born from inspiration and brought to life through extensive testing and refinement. Whether it's a whimsical fantasy piece or a practical everyday item, if an idea sparks my interest, I'll turn it into reality. I hope you'll find joy and utility in my creations, just as I do in designing them. Happy printing! |

Printing Instructions
This model is organized into 5 print plates to simplify printing, color planning and assembly.
Using the provided print profile is recommended. All settings, brims and orientations are already optimized to keep parts stable and ensure a clean result.
If printing manually, most parts work well with:
- 0.2 mm layer height
- 3 walls
- Lightning infill
- No supports
The dome and base print better using ~5% gyroid infill, which improves structural stability.
The dome was designed to bridge cleanly and prints without supports.
Tentacles can optionally be printed in vase/spiral mode if you want to minimize visible seam lines.
Print Plates Overview
- Plate 1 — Base Structure
Base shell, lid and crank housing. Using a contrasting color helps visually separate the base from the jelly. - Plate 2 — Base Drive System
Internal gears and mechanical components inside the base. Light colors can improve brightness when using a translucent base. - Plate 3 — Jelly Body
Dome, tentacle mounts and visible jelly parts. Translucent or silk filaments create the best underwater effect. - Plate 4 — Jelly Gear Core
Internal motion gears inside the jelly mechanism. Light colors can improve brightness when using a translucent jelly. - Plate 5 — Central Column
Connects the jelly to the base. Transparent filament creates the best floating effect.

Important Notes
The jelly mechanism uses two types of gears and tentacles.
See the diagram below for a visual guide.

- 4 Internal parts (I)
- 8 External parts (O)
Each gear and tentacle is marked with I or O for easy identification.
Gears only fit correctly in their intended position:
- Internal gears (I) go on the inner ring
- External gears (O) go on the outer ring
Tentacles can technically fit in any slot, but the intended visual effect is achieved using:
- 4 internal tentacles (I)
- 8 external tentacles (O)
