Vortex bee escape

thingiverse

This is a triangular bee escape design. Drill a fifty-millimeter hole in the center of an escape board and attach the escape underneath it. Due to the current time of year, I won't have the opportunity to test this design until next season, so feedback from experienced beekeepers with longer seasons would be greatly appreciated. The openings may be too narrow for drones to pass through effectively, making them suitable for use only after drone expulsion is complete. Given my use of 4.9 millimeter comb, the openings might be slightly constrictive for five-point-three millimeter bees; however, I believe it should still function adequately.
