June 2019 SimplePro frame acquisition.
Brook Drumm was moving and had these 'kits' along with most likely
a plethora of other printrbot remaining inventory; anyway to make a short story too long.
I purchased one along with a Gearhead Extruder Assembly.
It made perfect sense at the moment as my original printrbot
Simple Metal is exhibiting signs of age.
This probably won't be addressed until winter 2019-20....
Truth be told there are enough other xtra parts on hand here to
allow another option of just building a FrankenPrinter
without scavenging the original Simple Metal.

Late August 2019 Have compiled most everything necessary to assemble this
without dismantling any other printer, this appears to be the winter 2019-20 project.
