The single most useful print is just a simple cylinder to repair a broken knob on a nearly brand new kitchen stove. A new knob cost $35 at the time and had a 2 month lead time from the factory, (it was during the covid lock down).
It took longer to turn on my computer and start up my CAD program than it did to design the repair part for the knob. 30 minutes later, I had the sleeve printed and super glued over the broken part and the knob reinstalled on the stove.
That’s been 7 years ago, the repaired knob is still there and in use daily. And one more knob got the same treatment. It probably took less than 10 cents of PLA and electricity for both repairs.
