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
(blue: standard infill and outer layers; green: 5mm infill spacing and 1 outer layer; yellow: standard infill and 4 outer layers)


Annotations for further changes
O-ring holder needs higher walls and smaller diameter; screw stop either has to get bigger or moved 2mm; gripping surface will probably loose the flat area and get completely rounded for better printability with less supports.
