Filament spool hook

This was the first thing I ever designed. I couldn't find anything that suited my needs so came up with a very simple solution. These are the perfect height for a variety of spools and can be easily adjusted.

The holes are a little bigger than I'd have liked but I've mounted them with washers anyway. After two months of daily use they're still as rigid as day one.

I printed mine at 30% but increase the infill if you're unsure!
