Filament Duck 1.1 - filament spool stand [Challenge update]

It's not that easy to find a solution to make sure the filament doesn't get stuck during a print. After hours of browsing thingiverse, failing with a couple of spool holder designs and a ton of canceled prints because of filaments knots I started from scratch and came up with a new approach: the filament duck ("inspired" by a duckbill).

- **no fiddling around on the back of the printer**
- **easy to use**
- **great form factor**
- **no supports**
- **no assembly**
- **no extra parts
