So this adapter is for a 43ish mm vacuum hose to connect to the Bestway 27 mm hole for vacuuming. the small end is a touch small but if you use a real hose clamp it will work fine. the model i mad does have a few errors, I'm sure someone can fix them but the file prints just fine. This is a test I may end up printing out of ASA and I'll upload the file for that if I do.
