Beyond the easy answers of replicating the machine itself or covering basic needs, I think it would be interesting to make a super computer with a small form factor capable of mind uploading. Then you print a replacement body in a position that fits within a cubic meter and presumably you can extend your life for a bit. A simpler alternative would be to replicate medicines that have been shown to extend healthspans in the short term and just take them in the recommended dosage when you need to.

Shadowrun or Eclipse Phase, either way it’s not good. I’d like the tech from the latter, but not the rest of the setting.
