But they’re still failed prints.

When I’m designing mechanical parts, it usually takes at least a half dozen prints to dial in all the dimensions. Saving one or two failures during that process would save a lot of time, and I’d still be able to test fit the completed “failures” and see if I got some of the numbers right.
