For any thread followers that have contemplated using the edge-mounted Delta BFB0512VHD-SP01 blower for a print cooler as I did in post EXTRUDER REBUILD AND NEW PRINT COOLER (Part 2 of 2), note that the blower is now obsolete. If a blower is needed, order one soon from available stock currently remaining at Digikey. I am not aware of a suitable replacement once that supply is gone.
