Spiral respooling spool

I pretty much exclusively use refills or filament that comes on cardboard spools and I haven't had the best luck with spool adapters in the OG AMS. So I decided to transition everything to respool spools… but I had trouble finding some that I liked. There are a load of good models on MakerWorld, but most of them have extra features that I don't need for my use case. So I set about designing a simple model that's quick to print, super lightweight in material use, and looks sharp to boot. At 110is
