Original Prusa i3 MK2/MK2S/MMU pinda probe cooler

thingiverse

The PINDA probe on the original PRUSA i3 MK2/S has a major flaw: when it warms up, it detects the bed too soon. This problem will be fixed by the upcoming PINDA 2, which actively accounts for the temperature of the probe. This issue is especially significant when printing materials that require high bed temperatures in an enclosure, particularly if a print is cancelled and restarted shortly afterward. This cooler helps resolve this issue by blowing unheated air from outside the enclosure over the PINDA during the bed heating cycle.
