Filament Acrylic Sheet hanger

I needed a quick way to mount a single spool inside my Ikea Lack enclosure. This fits over up to 3.5mm sheet and holds a single roll.  Needs a m3 screw up to 10mm long.  To install, I first attached the rod to the hanger, it should fit flush on the back side. Then attach the cap with up to a 10mm m3 screw.  Does not have to be that long, but I gave it at least 10mm in threads inside the rod.  Then I just pushed on my side window to flex it past the ceiling enough to slide the hanger over the top of it.
