Corner bee escape
thingiverse
This is a corner-mounted bee escape, requiring drillings of 50mm holes in each corner of an escape board and mounting the escape under each hole. Since it's already too late in the season for me to test them this year, any feedback from beekeepers with longer seasons would be highly appreciated. I believe the openings are too narrow to allow drones to escape, so they should be used after the drones have been expelled. I use 4.9mm comb, and while the openings might be tight for 5.3mm bees, I think it will still work.
