Change Log

As of 12/3/18 - known bugs are: positive bump endstop holder does not fit around motor just by 1 mm, whereas magnets worked before as they had play. Print Cooling Fan: needs nozzle optimization. X axis mounting: needs procedure optimization for axis tightness.

Hint: Note that to design new versions of the 3D printer, you want to use small, simple files. We have ones ~20k for each axis.

Note that D3D_Part_Library#Assembly_Index contains the simplified assemblies. These are to be used any time that a new version of the 3D printer is to be designed from scratch.
Simplified axis files - X, Y, Z - the smallest ones today are also used on the D3D CNC Circuit Mill
D3D Integration has files that are on the order of 5MB and 1MB for each axis. Still too large for prototyping.
