Sticky trap holder

thingiverse

A device designed to capture pesky fungus gnats or fruit flies is made up of two interlocking parts that are printed without any supporting material. Once these parts have been printed, they can be easily clipped together, and then the sticky paper can be trimmed down to a compact size similar to a credit card. This paper can then be inserted into a narrow groove created by the clipped-together pieces. I strongly advise against attempting to disassemble the two parts while they are still in their original state, as this can be somewhat challenging, especially if made from PLA plastic.
