Filament pusher

thingiverse

When I started using a mounted spool support on my 3D printer, I noticed the filament was hitting the printing board and as the thread was unwinding, it made unpleasant friction noises. So I created this filament pusher to make sure the material is guided to the extruder as smoothly as possible. This first version has quickly been designed using a computer-aided design software. V2 is on its way using a more advanced design tool. Please share your feedback on what could be improved. I tested the pusher only on my printer with PLA filament. If this design works on other printers and/or with other kinds of materials, let me know in the comments section and I'll update the description.
