These are very good working vacuum nozzles and a short extension (7-1/2") for a small shop vac. Some I found online were sturdy at the base but in vase mode at the top, not strong enough for most vacuuming so I designed my own. I printed in PETG for strength and it worked quite well. Also I printed standing on end with organic supports.
