at our university we are currently using the UM3. Somehow some students managed to clog the BB 0.4 nozzle quite heavily. With some effort I managed to unclog the nozzle, but for some time, we were unable to use the printer. To reduce these off-times, I wanted to buy some nozzles, so we just need to change them in case of urgent need. But this is somehow a bigger problem than I imagined, because it is not possible to buy nozzles from UM for the UM3. The only way is to buy a whole new print-core for over 110,- €. The offered nozzles for the UM2 are not compatible with the UM3. Does anybody by chance have a source for UM3-(BB 0.4)-nozzles?
Thanks a lot in advance.
