fruit fly trap

Thanks to Motsie for the original design. I changed it to make it printable without using supports. Start from the big side and it should work out fine. The wall thickness is about 0,7 mm. So it's just two parallel lines in each layer with a 0,4 mm nozzle. prints fast and uses less material.

Update: I added a skirt to the design. It helps the part staying attached to the print bed and prevents the trap from being shifted sideways on the glas.
