Prusa i3 Nuts and Bolts Hardware Kit

This is a complete set of nuts, bolts and washers for a Prusa i3 Single-Plate frame printer.  If you are building a box frame then some of the M3 nuts and bolts will be extra, and you will use wood screws (not supplied) to attach the axis mounts to your frame instead.  This kit also includes the necessary hardware for using either 623 (uses M3 bolts) or 624 (uses M4 bolts) idler bearings for the x and y axis, so you will have some additional nuts and bolts depending on which one you choose to use.  Items supplied in the following specifications and quantities per the iteration 3 wiki (Prusa i3 Buyers Guide).  We also include some 20mm M4 bolts (not in photo), along with additional washers and nuts in case you use a printed parts kit (like ours) that has the belt adjusters for the x-axis and y-axis.
