Hi blindfoldjump,

> cut up the form in a few pieces and then make some clean chamfers and fillets on the edges.

Well, if you cut some pieces and get some crisp simple sharp edges around the cut zone, those particular ones might have a chance to be filletable.

But filleting does not deal very well with surfaces that come close to being smooth to each other but are just slightly creased, so for example near the front bottom of your object here it's not a good situation for filleting:






It's also not great for filleting to have edges that suddenly bend and swoop right before they come to a juncture with other edges and there are many of those in your model as well.

Basically I wouldn't expect for filleting or chamfering to work on anything currently in that model but if you introduce some new simplified edges through some cuts those might have a chance.
