About this 3D model

The plastic parts that came with my i3 frame kit were unusable. And I wasn't able to print Prusa's original SCAD files from github very well. My other printer doesn't do long bridges well so I redesigned these parts to eliminate or at least minimize them. I was a little concerned about using zip-ties but they seem to work well in holding the X rods and LM8UU bearings. The extruder isn't modified much from the original except for the placement of mounting holes. I ended up moving them around to get a good fit to the X carriage. That led to the J-Head slot mount plate's bolt hole placement being asymmetrical. The laser cut holes for the Z rods were a bit oversized so I made a pair of supports. The Z rods are 12.5" versus the original 12" to accommodate them. Now that I think about it, I could have just printed the top header piece with a clamp built into it. The top left X rod support needs to be carved out quite a bit If I intend to use the full volume in the Z axis. The extruder motor will hit it when it's at or near the zero position in the X axis. Maybe I should think about making a smaller extruder.
