Customizable Bike "Trunk" Container Adaptor

As a Father's Day gift for my bicycle riding dad, I made him a custom designed container to hold a half-flat of strawberries (or whatever else he wants to bring home). It uses a 3D printed adapter pieces to slide into the bike rack behind the rear wheel, and connect to whatever container you want with 1/4" bolts and lock nuts. A carabineer keeps the container from sliding back out the rack. I used a Sterilite 4 Gallon Stacker Tote in my example, but nearly any container can be bolted to the adapters. More detailed instructions and assembly for my example are posted below. So if you have a father, or know someone else who likes riding bikes and want to bring more than what fits in your regular bike bag, you might just be able to make his day. Also, if you think this design is a cool bike accessory, you can support this design in Pinshape's bike accessory competition. https://pinshape.com/items/22668-3d-printed-customizable-bike-trunk-container-adaptor. .
