Plastic Reef #1: Random Anemone Generator

Creation's quality: 5.0/5 (1 vote)
Evaluation of members on the printability, utility, level of detail, etc.

3D model description


This one may be the first of a generative series based on reef structures (corals, anemones, etc..). I called 'Plastic reef' and it's just a lot of decorative stuff from some OpenScad experiments.

I don't know how many generators will made, i have a few that looks promising and eventually i'll upload here. Feedback and new ideas are well received.

As many of my generators, the Customizer produces 2 sightly variations based on parameters provided.

In this one, the customizer generates 5 files: One for the full anemone (tentacles+base in one single piece), 2 random tentacles and 2 random bases. You may choose your favorites and print.

I've used some code from Torleif's openscad website:

Hope you enjoy it.

Have fun!

0.2 it's ok


Doesn't matter

There's no 'toleration' margin between tentacles and base parts.

To have a good fit you may need adjusting your slicer parameters in order to compensate the excess of plastic.

Reducing flow, increasing XY scale of base in 1% or 2%, using 'Horizontal expasin' parameter (in Cura slicer) or just sanding the pieces until they fit.

No supports needed, the angle of tentacles is tweaked for avoid overhangs
