Designed and manufactured by me bee feeder resembles a school pencil case. The side and rear walls made of planks with cross section mm 60×10 each of them with the 4-mm deviation from the upper edge chose a circular saw, the groove depth of 4 mm the width of the groove was done such that the valve is cut from a glass, entered into it freely. Given its front wall height is 8 mm less than the side and rear.

Fresnel lens in the past, have found application mainly in large lighting fixtures type marine beacons and today is actively used, for example, in projectors, in viewfinders of cameras and flashbulbs. Small thickness of such a lens allows you to release them in the form of plastic transparent rulers bookmarks, which are usually used by people with low vision read small text.
