Tried to make an interesting and garden looking fly trap. Hope you like this one!

Add apple vinegar to glass and just set this top of your glass. Close with cap part when there's no flies :)

Ideal for use with, for example, a jar of baby food. The model is easily scalable, so you can use any size glass.

I recommend using a brim, even though it's annoying to remove :D

Make sure you have a good adhesion if you don't use a brim.

I would greatly appreciate it if you could share your comments and photos!
