I had an Idea to create a design to match the Fan Grill and cable guide design (http://www.thingiverse.com/thing:1404598) but it just wasn't working. So I came up with this re-remix to pimp up my Printrbot.
I completely remastered the original design in Fusion 360, rounding the corners and holes as they had a low segment count (probably originally designed in sketchup). A simple extruded text label for the locking lever and a Large PrintrBot Logo.
the Logo has some locating pins on the back and is superglued on to the base. M3 screws attach the lever and linkage.
Use a brim for the Base to prevent warping. Only the lever requires supports.
The Locating holes might need a 2mm drill to open them up.
No need to drill right through just 1mm or so
