Printing bugetary considerations

What’s the best way to provide a cost effective print to the customer:
LetoLabs Cluster cloud bowl for example is shown as having a printed price of around $1058, yet there is very little material in it.

Have you got a basic formula we can use to evaluate our models prior to uploading?

For example, if LetoLabs nested smaller bowls within the large on, the same printer volume would be used (assuming a dedicated print), and not much more material. Likewise, merged customer product packing could potentially lower your build costs and be passed on to the customer increasing competitiveness.

Does the site need an enclosed volume calculator?
