Recommends: I'll recommend you take a look at my new
Flat Filament Spool Holder - No spring- The Claw remake.
I needed a new Spoolholder for my version of "Ultimaker 2 Aluminum Extrusion 3D printer" http://www.thingiverse.com/thing:811271 and a way to mount it filament spool to my Extrusions and created this one.
I used the "low-friction-um2-spoolholder" https://www.youmagine.com/designs/low-friction-um2-spoolholder as my source, but ended up changing everything. Everything is slimmed down, reinforced and basically reinvented even though they look pretty much the same at a glance.
My build does away with the center spacer and instead inserts the Bearings from either end. It makes for much stronger parts and eliminates the risk of pushing out the ends of the pieces if you overtighten them.
The finger nut has been slimmed down to make a less obtrusive part.
The inner spoolholder have had some finger-knobs added to ease the tightening/loosening action.

Updated instructions here.
In the files you basically find 2 models, where I consider the first model as deprecated - I keep it as the source
Deprectated files:
reinforced_center_threadding_for_spoolholder_608zz_226mm.stl
reinforced_base_with_fingergrib_for_spoolholder608zz_226mm.stl
Edit: 7. september 2015:
Added a version of the mount without middle and side-guides. Works the same and I recommend printing with 100% infill (for the mount).
Added final version of the "slimmed nut"
Added 3 spacers which you might want to use between the Nut which goes against the Mount and between the base in order to reduce friction slightly. If you use a locking nut, you want to use the 5mm version.
Edit the 13th september 2015
I added 2 new models where the Base and *Center parts are combined into 1: inner part 6mm-basehole.stl and inner part 15mm-basehole.stl
The difference in the two parts
The depth of the hole in the base, facing your printer: One is 6mm deep, intended for your bearing to sit in there with 1mm going outside to make a bit of space between the base and the printer. The other part has 15mm hole intented for both the bearing and an M8 nut if that fits your build
