A hook that holds the catcher by the neck
An adhesive plate with a forked retaining hook that cradles an electric fly catcher by the handle neck, so the catcher hangs off the wall instead of resting on a shelf or hanging from a nail. The prongs bend inward at the tips, which keeps the neck seated rather than letting the catcher swing off.
The plate defaults to 72 × 70 mm and 4 mm thick with 5 mm corners. The rear posts sit 48 mm apart between the inner faces and the prongs 70 mm apart, with the fork reaching 60 mm out from the plate and its roots 40 mm above the plate bottom. Prongs are 10 mm wide and 12 mm thick, tapering to 20 mm roots, with a 0.8 mm bevel on the edges and tips.
The retaining mouth closes to 58 mm between the tips, which holds a typical catcher neck while letting the head pass over the tips when you hang it up. The fork meets the plate through tapered hulls so the adhesive face carries the load; double-sided tape or foam tape on the plate back is what holds the whole mount. Measure the neck of your own catcher before printing.
