Fixing new parasol

Wife bought new parasol for very cheap to take to the beach: got the one missing the screw top holding the fabric in place…

Choice to either drive 10km and return it or…

15 minutes in CAD, 45 minutes on printer with perhaps 5 minutes slicing ;-)

Don't know if standardized - probably is, or wouldn't have been that cheap: inner diameter about one inch, thread with a pitch of 3.8mm (no idea which fraction of an inch that would be).

Perhaps someone else can use it!
