Use these nozzles with a standard ball pump and a Schrader pump for filling vessels with a wider hole (6.5mm - 11mm).
I printed this with a layer height adjustment. 0.0mm-8.0mm was printed with 0.1mm. The rest was 0.2mm SPEED on the MK3S+.
I printed it with the tip of the nozzle on the bed plate with a brim and no supports.
The OG creator recommended PETG, but since this is larger and has more strength I used PLA and it worked great.
I used this to pump up both and air mattress and an exercise ball and it worked great with little air loss.
The author remixed this model.
I expanded the needle to make it a nozzle for filling up an air mattress or a exercise ball. This will fit into a hole that is 6.5mm to 11mm in diameter.
