MK2 Frame upgrade

12/26/17 Added edge guide to drill guide.

12/18/17 Replaced corner braces and rear y-rod holders with mirrored pairs. Rplaced Rambo adapter (attaches RAMBO case to extrusion for stiffness) and PSU (fits clone) with versions with slotted screw hols for extrusion attachment.

12/17/17 updated drill guide to Mk3 spacing. Replaced RAMBO case with new cable grips (use mk2.5 covers). Do NOT use y-idler until re-done as the lenght is wrong compared to the Mk3 version.

10/26/17 modified belt holder to allow bed to go back fully. Rear extrusion should have been 5mm longer and front ones shorter. clone is assembled and passed self-test.

10/22/17 files refreshed

This started as a cost saving alternative to the Haribo/Zaribo mods. The intension was to re-use as much as possible of the MK2 while discarding the allthread. Then the MK3 came out and I modified my design to follow his. This is in no way official!!! This is stricltly my version. The parts have only been tested on a clone
