Bee hive frame with side lever

Bee hive frame hooks with side lever strongly inspired by Phaedrux (thanks!) https://www.thingiverse.com/thing:2753009 with added support lever on the outside. It prevents the tilting of the hooks so that the frame can not fall out when working with bees. Created for two widths of the hive wall, 28 mm and 25 mm. Print two mirror turned pieces (R and L piece) for each size, levers are meant to be on the outside when hooked on the hive as on the photo. I created version for Langstroth hives with thinner wall too, if somebody needs.
