Why I test-print everything twice

Every model in the shop gets printed at least twice before it’s listed — once on my well-tuned printer, and once on the crustiest profile I keep around specifically to be difficult.

The first print tells you the model works. The second tells you it wasn’t luck. A surprising number of “fine” models fail the second pass: a bridge that only worked because of a fan setting, a tolerance that only fit because of one slicer’s compensation.

If you sell models, your customers are effectively the second printer. Better that you find out first.
