well at 150 and 0.4mm the spools print fine (not pretty, but 100% functional) and in an hour and 6 minutes.
Generally the actual print speed probably averages about half the maximum. For this particulay item, only the 2nd and third base layers are printed at maximum speed. The rest is all outline and given that it's all underhang and overhang - figure half speed is damn good. The little turbo nozzle for the fan setup is obviously doing a good job. Cooling those outward sloping layers at that resolution and print speed is not simple. Plus upped the print-temp to 215.

But getting a thing 50mm high and 150mm diameter in an hour - is no mean feat :-)

First mosfet arrived today. I have no clue if this is the £3 or the £6 one.
Have to wait for the second one and see if there are any discernible differences.

The cheaper one I'll fit to Alexa.
