Paradise Honey Nucleus box entrance reducer

These always end up getting lost, so I thought, of course, of 3d printing them

It has an extra handle that aids in opening and closing more easily while on the field.

The original has a small lip on the back. I don't know its exact function or if it has any at all…but for printability, laying flat on its back, I decided not to include it. It doesn't seem to affect functionality at all.

Better printed in PETG than PLA. Ideally ABS for maximum durability.

Description from the original product:

A pair of entrance reducers similar to the version used on our hives. Used inverted, to close off the entrance completely or normal, to restrict to a bee-sized gap. 

A pair of entrance reducers similar to the version used on our hives. Used inverted, they close off the entrance completely but in normal use they reduce the entrance to a bee space high which keeps out mice and helps the bees defend a smaller entrance. They are sold as a pair as our nuc boxes have two entrances as standard.
