Rectangle Hair Dryer Adapter

Summary My GF wanted to use a hair dryer accessory but the thing was that she has a rectangular hair dryer, not the standard round one. Thus, instead of paying to get a new one, I decided to make an adapter for it. I printed this using PETG, my very first time using it, because i thought that the heat, even on the lowest setting would melt PLA. I wont test it out but will assume its true. --Issue-- Even on the lowest setting, the power if the blower pushes against the adapter. I or someone else needs to find away to make it so the adapter does not "fly off." I was thinking of using a old wire hanger or something to wrap both parts together I am the owner of https://www.neocrisis.com/
