Single-Piece Patton Seat Extender

Patton seat extender single-piece adaptation of Rawnei's 2-piece Beidou design. After trying Rawnei's model, I found that the rear half half was prone to opening when standing up (sliding off the back), and that the gap between the two halves, while small, became uncomfortable during long rides. I remodled the 33mm seat extender into a single piece. This single piece design ensures easy access to the trolly handle. Apply only a small portion of velcro to the front of the extender (as opposed to covering the entire surface) and use the small carve out/lip that allows finger tips to easily pull upwards on the seat (see images). Print in TPU and apply velcro to the both halves of the Beidou seat. Apply velcro to both halves. For TPU types: 95A is soft, and 98A is hard: I've tried both, it comes down to personal preference. This is not compatible with A1/mini due to size limitations. Rawnei's 2-piece design is better suited for A1/mini.
