Pump to air line adapter

thingiverse

I have a Guppy Tank and had a batch of babies (fry) in a breeder box in my tank, after 1 day i noticed the water doesnt actually circulate through the breeder box as when i feed them the food would just sit as a layer on top of the water. well thats no good so i built this adapter to connect a Tetra whisper 3i filter pump to an air line to allow me to create a minor circulation through the breeder box. i also then created a flow nozzle so instead of a stream and heavy current i was able to disperse the flow for gentle current for the fry, i had to create a 2nd one as the 1st is too large for the actual flow of my pump so i made the 2nd smaller flow nozzle. this slips on the side of the breeder box and connects to the other end of the air line. printable without supports but i do select make overhangs printable.
