My oil tank sensor is registering 47.5°C inside its black plastic case in the sun... Its only PLA...



I plonked a failed PETG print outdoors earlier just to see how it fares, I think it's cooled down since then ...

Well the sensor is still working. Its in the shade now at a reasonable

33.8°C

UFH heated areas downstairs at a cool 25°C.

Upstairs with windows open its a slightly stuffy 30°C.

Local airbase says its 32°C

Nothing to get excited about really

Going down to airfields south of London its 34°C

No doubt at Kew gardens it will be a 'record 45°C'

A glorious day all in all. To do the square root of sweet fanny adams. I may get a cold drink later....
