Fusion
Converting faceted mesh models into Solids is often a bad idea. Can you share the model in original .stl format ?
As Peter (@TrippyLighting) already mentioned, only in special cases (further 3D editing) it makes sense.
Here's BREP of this file. Filesize 5766 kB as STL, 33653 KB as F3d.

First thing i would do is before trying to convert from an STL to a solid check the scale of your model. I have noticed almost always the model is opened in cm vs the mm i would usually design something in. This makes the model 10 times larger than intended. If you scale it down to the correct scale, a lot of times this makes the conversion to solid go a lot smoother. At least this works for me.
I guess you're uploading your models through Fusion's data panel, and yes the online translators default to CM. If you use insert mesh Fusion will default to document units and you also have the option to override the units on the insert dialog.

Often the best way to do this in a CAD application is to first re-mesh the triangulated scan data into a quad mesh.
That quad mesh then can be imported into Fusion 360, converted into a T-Spline and then BRep.
the large advantage over a faceted BRep created by directly converting a mesh into a BRep is that the result is not faceted .
I have created this tutorial a few years ago and it has worked many times, although in my current attempt Fusion 360 fails to convert the mesh into a T-Spline it is still worth trying:
That's only a big deal with respect to filesize.
In Mesh environment -> Modify -> Convert Mesh with Method Faceted. After some time you'll get a BREP with thousands of tiny faces.
With the result a boolean cut could be done versus a solid box. But the real challenge will be parting line creation for the cavity.
Shortly after writing: Peter has been there already.

Attached is a model with a quad-mesh face count around 20,000, created with the workflow in the tutorial.
That high face count might not be needed to retain the detail of the scanned mesh.

Ik really need the solid to make a castmold for it which will be printed on a 3d printer. You can't do it when it is still a mesh (sadly enough).
This can generally can be done entirely using a mesh-only based workflow. It would not NOT involve Fusion 360!
