Reduce display width

Hello,

I use this plugin so that the customer can see the products in 3D before purchasing them.
The problem is, I can’t reduce the width of my 3D display frame. The products I want to see 3D are variable products. So I placed the shortcode in the description of each product variation so that the 3D is loaded according to the user’s choices. I tried to change the values ??of “aspect ratio” and “initial offset” but it doesn’t work. Looking at the support, I saw that some were saying that you have to put the shortcode in a table for the 3D to fit into a cell. But that doesn’t work either.
Can you help me please ?
