No doubt it's going to help. ABS warps so badly that I've switched to PET, but, you give up smoothing with Acetone. As dangerous as that is, it's still less dangerous and the chemicals to smooth PET. Lately I've even had bad warping with PET and it really is warp friendly. So, I'm thinking about an enclosure too. That's the reason I ask. I don't want to go through all the work and still say, "crap, that warped." I'll be curious to hear more results from you. I'd like to see if you can print that same part in ABS exactly the way you did before you built the enclosure and see if the warp is mitigated.
