Butterfly bookends

My wife wanted a butterfly bookend that has larger butterflies and easy to assemble features with wide and long book supports. -The bookends have a radius built in to increase strength.-The bookends are wide and long enough to support books of various sizes. -The butterfly can easily be attached with a little superglue. -The models are interchangeable.I recommend printing the butterfly and square negative face down on the plate and use support PLA or PETG as the interface layer which will peel off nicely. The butterfly can be printed on either side and will be made a lot stronger than trying to print with supports (No supports necessary this way).
