I saw some nice fruit fly trap designs here on thingiverse but wanted to try building my own.

Sorry for adding one more to the long row!

This on fits on a drinking glas with 7.6 cm outer diameter and can be scaled up or down to a certain extent (the holes might be to big or small in the end or the bottom part might not fit over the bulge of the glas edge any more)

The lid prints upside down but both the bottom and top part can be printed as they are without any need for support.

Bottom or bottom + top may work seperately but the lid gives a funny finish.

I'd highly appreciate any comment and please post a picture in case you actually printed one of my designs. Thank you!
