Larger Spool Holder for 5/16 SAE Rod

This is a slightly larger variation of the 5/16 threaded rod spool holder from http://www.thingiverse.com/thing:781495 I designed from scratch. It should still take a 22mm OD x 8 mm ID bearing but since I don't use them it may require modification for them to fit.

It allows for a spool of plastic to fit on your roller that has a larger diameter spool opening. All the other parts can be printed from lewis1914's design and worked well for my spools. I found an extra bolt and washer on the end
