Ervu Vessel v1.2

Designed by: Dean Hewson




With Ervu Vessel, you can create a 3D model of a vessel, like a plate, bowl, cup or vase.

You’re able to set a starting shape, then push and pull it’s form using up to 4 simulated electrical charges and the electric field that exists between them.

Once you’ve downloaded your model, there are a few things you could do with it. However, Ervu is still new and in development. It is likely some tweaks and changes will be needed before your Ervu Vessel could be manufactured. Use the ‘Add to Cart’ options above to get one on one help, and post to the Group about your problems so we can improve the Ervu Vessel toolkit.

This user toolkit has 4 main steps. You switch between steps using a dropdown select box on the toolkit (for now – in future versions this will be clearer).

  1. Create a base shape
  2. Form the shape with ‘electrons’
  3. Give the shape thickness
  4. Export it

To start making your outcome, click on the User toolkit button. Read our guide to the basics of using a user toolkit here. Remember; make small changes first to get a feel for what each slider changes, and hit the full screen option in the top right of the toolkit if you want to see it more clearly. Please also remember to send the parameters to Testbatch as well as yourself (using the buttons at the bottom of the toolkit).

Step 1

Create a Base Shape

The pink guide curve is controlled by three user editable points. They are shown with 2, 3 and 4 circles in the user toolkit.

A variety of available starting points

Point 1

This is the ‘origin’ – the very middle of it all. It’s where the X, Y and Z axes meet (or put another way, all equal 0).

Point 2

Left <-> Right

P2 L<->R
This point is restricted to the ground, and can be right next to point 1, or a bit further out.

Point 2 goes from left to right


Point 3

Left <-> Right

P3 L<->R
Point 3 left and right

Up <-> Down

P3 U<->D
Pt 3 up and down

Point 4

Left <-> Right

P4 L<->R

Point 4 left and right


Up <-> Down

Step 2

Form the shape with ‘electrons’

The next step is to start pushing and pulling the base form using electrons. You start with 2 electrons active; you can have up to 4.

Positive charge electrons are shown in red, negative in blue. You can change their charge, their height, the width of the circle they sit on, and where they sit on that circle around your form. You can also change their overall strength with a slider near the bottom of the toolkit.

The green circles show which number electron you are editing, and the size of the red and blue lines coming from those rings show the relative strength of the field in that direction. The stronger the field, the more pushing or pulling will be done to your base form.

Whether a charge is positive or negative makes a big difference – the size of the charge sometimes matters, and sometimes doesn’t.

Step 3

Give the shape thickness

The last step is to give your form a bit of thickness, so it turns from a surface into something with mass that could actually be made. If you want to 3D print your object, setting the thickness high enough such that it can actually be made is vital.

Spend some of your community currency and select the 3D printing quote or customisation options above to start a conversation with us about how you could go about going from a digital model to something you can hold.

Step 4

Export it

The last buttons on the toolkit let you download the model, send us the parameters (essential for us to collect data to carry on this project), send yourself the parameters and a link to the outcome (so you can come back and recreate your model), and/or download the model directly.



User Toolkit

Create a bowl, plate or vase with the Ervu User Toolkit. Playing with this toolkit is easiest if you make it full screen; tap the icon in the top right of the view to make it grow.

When you are done, please make sure you hit the buttons at the bottom to send the parameters to Testbatch, to yourself and if you, download the model. Then depending on what you want to do next, join the group discussion about Ervu to help shape it, or purchase one of the above options to start a discussion about 3D printing it, or customising it further.

Please fill this in as soon as you finish your outcome and send your parameters to Testbatch.

Can you describe the 'vibe' of your outcome?
