“3D Printing Product” checkbox on Variable product

Hello,

To plugin installed well, I can upload and see STL files, get email for quote etc… But I can’t get the price as the weight/area/volume are not estimated. Only the box volume is calculated.

Material Volume:0.00 cm3
Surface Area: 0.00 cm2
Model Weight: 0.00 g

Box Volume: 57.50 cm3

I noticed after reading the documentation that I have no “3D Printing Product” checkbox on Variable product, I dident find a way to get it, even after disable/enable th plugin and reinstalling it. I don’ tknow if it is linked with my problem.
