Hello Krthk85g,
I have a question :
- Why is it needed to have a ThingMark so big ?
I suppose that when ThingMark is not completly in screen, tracking is lost.
A quick solution can be to enable in 3D Container, Persist Map.
More details here :

To control the size of 3D Model, we can play with 2 Properties.
- Size of ThingMark
- Size of 3D Model
By the way, we have a relationship between ThingMark size in real world and size of 3D Model.
So, it is needed to be carreful to keep same size of 3D Model vs real product.
I would recommand to read these articles and this link to Help Center about scale and size :
