Long over due Filament Clip from 3DQF, We have been planning this for months and never getting around to it, thankfully this is finally done :-).
How to use
Place the filament in the clip then rotate the clip over the top edge of our card spool and into the centre of the tin cup, apply a small amount of pressure on the clip head and it will snap into the axle hole.
To un-clip place your finger inside the axle hole and genitally flick the clip out.
Hope this solves a problem, over the next few month all our filament will be coming with them but this is for all the roll's out there without one :-) .
Great little mount for our filament and takes only 16 mins to print !!! 10% infill is perfect for it.
