Bee Entrance Guard

This bee entrance guard is based on reading [Robbing screen designs part 9](https://scientificbeekeeping.com/robbing-screens-part-9-designing-a-robbing-screen-that-works-in-conjunction-with-the-colonys-guard-bees/); I've tried to capture what was described and shown. Randy mentions preferring actual mesh, so this design is meant to work with 1/4" hardware cloth or other insect netting. The caps *should* press-fit in to hold the screen, but a touch of glue may be needed. The photo shows my very first version which didn't yet have an effective hardware cloth mounting solution.

This is sized for an 8 frame Langstroth hive.

These should be printed in PETG, since I have seen PLA parts get distorted quite frequently.
