Micro-Mesh Sanding Pad Double Holder

My original here http://www.thingiverse.com/thing:37071 was a single holder that was very popular. I decided to make it a little taller (+1 more pad) and also double sided. First reason for the double sided was I have extra pads (these things are great). Second reason is that if you are going to go through all the grits on a project then you have a place to put the grits you have already used. In other words, move them from one side to the other as you use them working your was from the lowest grit to the highest. By the way, best place to get these pads is here http://www.ebay.com/itm/321639895967?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
