Why is my 3D model embedding incorrectly on my website?

I have a 3D model on Sketchfab that I’ll like to embed onto my website, however, once the embed code is pasted in, the model appears too small and all the way to the left. Example can be found at the bottom of this page: https://www.tailormadedesigns.co.uk/pages/design-services

The embed code is:

J31152B by Tailor-made Designs on Sketchfab

Any easy solutions? This worked on our previous website using squarespace, but seems to be an issue here.
