This is a fruit fly trap using one 60x60mm fan, tested with 12v and 5v USB fans both works well, although the 5v isn't as loud.
This works both active (fan on) and passive (fan off) because the liquid has a drop of dishsoap in it to remove the surface tension.
If you print the Outer fan assembly n bait you can put a small piece of fruit or banana peel as bait in the cup, although the fan then has to be on at all time when using the bait cup.
The liquid consits of a drop of dish soap, applecider vinegar or white/red wine topped off once in a while with water to keep it from drying out, especially if it's warm. Replace when needed.
Needed materials:
4 pcs of M4 screws to mount it all together, length depends of with or without bait cup or not and thickness of fan used.
1 pcs 60x60mm fan & powersupply for said fan.
1 Glass jar (included is two types of sizes on the jar, ~64,8mm and ~68mm)
IMPORTANT
Pause print to insert mesh then cut out middle hole, this way even if the flies don't get stuck in the liquid can't get back out through the exhaust.
Alternatively wrap a mesh round the base ovet the exhaust ports after print to prevent them from entering/exiting through the sides.
