Designing a 3D printable "tentacle" vase with SelfCad

in #printing3dlast year

Hello hello, fellow steemians.

Today, I'm bringing you a design tutorial using the popular SelfCAD online 3D design tool.

The idea

After walking around Andorra La Vella yesterday, I came upon a realtively well hidden building courtyard that had several sculptures in it:

These sculptures reminded me that there was currently a competition going on over on MyMiniFactory, organized by SelfCAD.

Given the competition has 3 themes (Character, Architectural/interior or an Engineering design) for objects designed using the SelfCAD tool, I decided to start out with an Interior design.

Starter shape

To start the design, I looked at the available shape generators:

I was hesitating a bit betwen the Custom Shape Generator, and trying to use the "Spiral" generator to make something interesting.

After playing a bit with the Shape Generator

I realized this really didn't have the oomph I was looking for...

So, I returned to the Spiral generator:

After tweaking the overall appearance of the spiral, I already had a vision for what I wanted to do with it !

So, I went off to use one of the coolest tools selfCAD has, the Copy Offset tool !

This tool has options for creating a number of copies, differentiating them from the original by moving, rotating, pivoting, scaling... the copies in relation to the original. lots of possibilities in there.

I kept it pretty simple, using the Pivot tool to create several copies

After adjusting the copy number so that the majority of the future model would be watertight, I used the Stitch and Scoop tool to fuse together the copies into a single solid model:

After that, I played with some experimental versions...

But I ultimately ended up deciding on cutting off the bottom ends, filling it up with a cylinder, then creating two separate versions:

Then I made the variants, by cutting the top of one of the two copies:

And voila, we've got the Swirling Cup, and Swirling Vase :

Here's the model on MyMiniFactory

Note: I'll update this post with printed versions as soon as I'm back home with my printer, in about a week's time (~ Friday the 29th)

Pretty cool but I have to say I was hoping for more tentacles when I read the title :) I think I was picturing something more Cthulhu-ian . Cool to see the design process and some of the capabilities of the software though.
