Robo 3D Oiler

Printed the original Oiler (http://www.thingiverse.com/thing:1374087) first and it fit so tight in the slot on the top of my Robo R1 +PLUS that it would not slide around when the Extruder moved.

So I reverse engineered from the STL file and created this Oiler instead. Now the Oiler slides around on the top.
