Replacement for Dyson v7 and v8 handheld vacuum cleaners. Replaces the original dust bin locking button. This part requires use of the original spring. Print in ABS or PETG for strength, however PLA works just fine. .1 or .08 layer height and .4mm nozzle or smaller is necessary for an appropriate fit, resin print would work best. Print with normal supports. A replacement for this part is nearly $20, and it doesn't even come from Dyson. A PLA print of this is three cents. The file is available in .stl and .3mf
