not that I know of. it’s going to be a lot of material if you print it, btw.
regarding dust: the two biggest vectors for dust on a 16n are jack sockets and faders. dust on the components is largely irrelevant. so: even if you box in the sides, you’re still going to have the main dust vectors on the object exposed, and those are places where dust is meaningful - scratchy faders, ropey audio contacts.
enclosures would protect the sides/innards a bit against things like spillage, however.
