Razor's Kappy 150mm bed parts

This is Razor's 150 x 150mm bed carriage split in freecad to make it easier to print on a smaller printable area. Applying CA glue across the entire surface of the mid sections and into the holes for the left and right sections to connect into seems to give a sturdy build.

There is an original version in 4 parts and then a newer version which contain some small edits, a 2mm wider spacer base, a spacer insert so they don't fall off and 2 zip tie points for anchor anchoring the bed's wires so they don't pull on the heater.
