WAVECUER cup older

My wife just got a Wavecuer garden seat/kneeler and likes to have ice tea nearby while she is working so I designed this cup holder to readily affix to the seat to keep her tea handy. I made it in 3 parts that press together so that I could print them without adhesion or support and make them as strong as possible. I print with PETG, but PLA will probably work as well if you keep it out of a hot car.
