I used the original spool rack for a over a year and then out of nowhere it broke and all my spools came crashing down. The exact spot it broke was a thin spot underneath where the rod sits in the well. I like this design, and didn't really want to try anything else, but knew if I stayed with this form factor that spot on the bracket would need to be thickened up. So I did, and it seems much sturdier now. So here is the remix for anyone else who may be using this to hold more-than-is-probably-safe numbers of filament spools, like me, and thus needs a bracket to suit our dangerously careless storage tendencies...
