This is a vacuum extension tip to fit all standard 1-¼" (1.25", 38.1mm) vacuum nozzles, such as the Ryobi PCL705 shown here.

I couldnt find a long and skinny nozzle to reach into the printer to get all the nooks and crannies. Print in vase mode. Its a snug fit on the vacuum, PLA or PETG shoue be fine.
