Anet A6 Main Frame

I drew up the Anet A6 primary components before putting it together, in case I need to upgrade any of the parts to aluminum later. I figure it might be useful to someone here. Let me know if any of the dimensions are off or if there are any other pieces I need to focus on.

Future plans for the models include:
-Finish drawing all the acrylic parts, including the X axis carriage parts.
-Source/include, all available hardware in the model.

I know not all the dimensions are perfect but most of them match up pretty close.

I have also included a file for screen spacers (mine were too short)

(How does this community not support STEP files?)
