Air matress pump to inflatable toy coupling

An air mattress developed a leak, but the pump was still fine. I figured it would work with a hand-operated inflatable toy pump, as long as I printed a coupling that fit both pieces. The large end fits a Serta air mattress pump (Intertek 3030409), and the small end fits Kwik-Tech AHP-1 Air Head Double Action Hand Pump nozzles. Also works for deflating!
