Frontrunner Rack Nut Holder

Moin moin everybody.I have a Frontrunner Roofrack. Installed some stuff to it. But i had a small problem. After unscrewing the stuff. The nuts get “lost”. The screw didn't catch the nut.So i made simple holder. It keeps the nut high enough. Also there is a 9mm hole. So no problem with longer screws. And a drainchannel on the bottom.Printed mine in ASA. No need for high support. Used standard SuperSlicer Settings. Happy printing.
