Don't have enough counter or table space to stash all of your filament spools? Tired of taking out the rod of your current holder just to get a spool every time you want to change filament? Well then just print out a few of these, add a spanner rod and your problems are solved! Each bracket screws into a wall stud and can support multiple spools of your favorite filament! 2 Brackets across studs 16" on center will hold 6 - 1kg filament spools. Please see instructions for more details. Happy Printing!!
