Lulzbot Mini 2 spool arm for ColorFabb Economy spools

We use the big 2.2 kg spools for our Ultimakers but when they run low, I switch them out and often have filament left over. I use the scraps in my Lulzbot Mini 2 but the big spools didn't fit so I remade the arm from Lulzbot open source plans. I use Fusion so I included the file if you want to modify it.
