Langstroth Beehive Frame - Deep Open  is a 3d printable beehive frame compatible with common Langstroth.  The size fit the deep box.  This frame is an open design that has groves to use with wax or plasic  insetrs that would go in the normal wood frames.  It also has holes in the sides to allow for use of strings to guide formation of natural comb without insert if you wish.  I also have other sizes and frame with the comb pattern integrated.  Check my other posted models for those.
