My H2C sits close to a wall, runs often, and needs its rear exhaust to breathe properly. Many existing solutions either blocked airflow, relied on glued magnets, or stuck too far out the back for a tight setup. Rather than compromise on those details, the goal became to design something simple, compact, and exhaust‑friendly that fits naturally into the H2C’s footprint and workflow. The end result is a small, two‑part bracket and bin that feels like an integrated accessory.
