Testing a newly arrived 3d printer and getting better tolerances out of the printer was this weeks goal. The original lid has more irregular features than a usual technical part, where geometrical forms are used and sizes seem to adhere to metric round numbers, making it harder to get it right the first time.
Printer calibration and test for the screwing portion.
Full print of the lid, fits nicely on the thermos
More tests with varying printer settings
