Sticky trap holder
thingiverse
A holder for sticky paper for catching fungus gnats or fruit flies. It is laid out to print without supports and then clip the two pieces together. Once clipped together you can cut the sticky paper down to credit card size and slide into the groove. I would not advise trying to un-clip the two pieces there is a bit of give but not with PLA.
