Bolt-on Printrbot Simple Metal 6" heat-bed feet

Info about changing the probe points in firmware can now be found on the INSTRUCTIONS page!

For some reason, no matter what plane I start the origin sketch on in Solidworks, it ends up in the wrong orientation.
Sorry about that.

I saw the design on here for a clip-on heat bed mount, but I would much prefer a hard-mounted solution, so I made these.
You will require 2 of each part.

This requires the Printrbot 6" aluminum bed part

I ended up constructing a heated bed for only $76 , compared to the $110+ of the Printrbot pre-made bed kit.
Using a Printrbot Thermistor (don't want to get that wrong!), and this heated bed
