... for the idler * 1 X 608 bearing (Skateboard bearing); * 1 X M8X20 piece of smooth bar, threaded bar or a bolt; * 4 X M4X45 bolts; - hex head will work best (they won't turn), and longer than 45 mm will be easier to assemble if you can find them. * 4 X M4 nuts; * 4 X M4 washers; * 4 X Springs - 1 mm diameter wire, wound to an OD of 10 mm, with 4 active coils. For a given filament drive force, you'll need about twice the spring force - ie, if you want 100 N of filament drive, your springs need to push with about 50 N each. NOTE: some users have theirs extruders working without this springs, but springs are recommended. * 16 M4 washers; - optional; 4 washers on each M4X45 idler bolt between the main block and the idler block will limit the idler travel and make reloading filament easier.

We printed all parts but found that we needed something to pressure the filament into the hobbed bolt. As far as I remember it didn't say how to do this, so we decided to make our own pressure block.
