8mm sleeve for indicator

I printed this Bracket http://www.thingiverse.com/thing:718768 but the Hole dia was more close to 9.5mm ,i needed more around 8mm for my indicator so i design a small sleeve ,you need to use your Dremel tool to get the bracket hole to fit (around 12mm)i needed to have a least 2mm wall thickness on the sleeve for it to be solid enought... then i glued the sleeve in and used my Dremel and files to bring all of it to a nice clean look and fit
