Filament Spool Wall Mount with Quick Snap Lock

Update: After hundreds of downloads over the last two yearsI decided to give the parts a new and smoother design. All new designs have the ending 'New' in the filename. SuperCone with better design to press the bearings in with less force. Lock Lever is user friendly rounded. Two versions for the Lock_Base: 'Wide' for more shrinking materials like ABS and usual printing quality, 'Narrow' if you print precisely and search for a klick feeling when close the lever. Two new 'SpoolBreak' parts to drag the filament spool a bit and keep the drag constantly. The 'Small' break touches only on the bearing and produces a little drag, the 'Big' rub the cone for a more significant effect. See pictures. All other parts are unchanged.

Usually my Spool Bearing Railway http://www.thingiverse.com/thing:1023865 is working very well, but for long hour (over night) prints I prefer to have a conventional wall mounted spool holder with very low friction. I searched for something and found this http://www.
