Hive entrance queen in/excluder

thingiverse

An excluder that goes over the entrance to a bee hive that prevents a queen leaving (or entering, I guess?) Useful for a capturing a swarm, as the rest of the bees won't leave without their queen. Printed in two parts to fit on my 200x200 bed. The height of the excluder is set in order to have three rows of slots, not by how high my entrance actually is. Don't @ me. On my printer, with a reasonably well-calibrated Z height, I can confirm that worker bees can pass through the grid. It is not recommended to leave such a thing on a hive long-term, as it could make it more difficult for bees to bring honey and pollen into the hive. https://github.com/tjhowse/queen_excluder
