Reel Box with Spacer
This is a remix of Skalla_J's Spool Storage Boxes http://www.thingiverse.com/thing:2103466 Only thing I changed was I added a spacer to the spool boxes as to give more separation for the items put in them. I like to keep one side for bolts, and the other for washers and nuts. I might try to add another slot but wanted to see how this design worked out first. Another slot may be to small for some peoples fingers to get into comfortably.
