Looks good!
There is this tutorial here, It’s a little out of date I think, but it should give you a general idea of how to start modding in items.
As for qubicle, there are free alternatives, if you are interested. However, if you do get qubicle, make sure you get an edition which has all the features you need. Basically, if you just want to import items you need an edition which exports .qb, but if you want to do custom animations make sure you get a version which exports .obj
I think Qubicle 2 for stonehearth will be able to do that, but I’m not sure as it’s not released yet.
