WARNING: SKETCHY
This simple print turns Parkside pump action drain cleaner (or similar, with a 20mm ball attachment) into a powerful and surprisingly precise single-shot nerf blaster.
Print in hard TPU or similar flexible material. Mine is Spectrum S-Flex 98A. Installation may require lube.
Be careful not to abuse the budget household appliance until it blows up. I use 4 pumps maximum, and never discharge it unloaded into thin air.
Don't shoot this one at anything animate. This packs a lot more punch than an off-the-shelf nerf blaster
Use at your own risk, since the appliance's manual specifically forbids using it for something other than cleaning toilets.
Oh, and mind the hygiene)
