Legs for beer crate

I designed the beer crate legs to be stackable. My design fits AA, AAA and empty battery crate. To put on, first set the ends of the legs in place and then forcefully push in the center, but with sensitivity so as not to break the crate (it happened to me that it was very difficult to attach the leg, in such cases you need patience). If it is too loose use glue. Print four at a one time.
