Electrical Box Twist Model

cults3d

I'm making my second attempt at grasping the operations in OpenSCAD.\nMy previous model of a 4" square electrical box with a raised plaster ring created in AutoCAD was exported to an STL file. However, I struggled to get emmett's heart gears file working, so I essentially dismantled the original cubeGears3 code http://www.thingiverse.com/thing:10483 until it ceased functioning as well. I rebuilt it sufficiently to achieve my desired outcome. I modified both the Gear1 and Gear2 modules to accept x and z rotation inputs (1 or 2), and then added some rotational code within those modules, the twogears module, and the assembly module to ensure they behaved properly for a non-cube object. I created an object module that loads a custom STL file and orients it for gear mashup.\n\nI'm still unclear about how the relationship between the overall model, the center, and pins is determined. To get around this, I simply tweaked the center cube until it looked right to me, then measured the necessary pin length and used the Pins library to create one. I haven't posted this revised code because I don't consider it a significant improvement over the original. I may post it if requested or if I can resolve some of the remaining bugs.\nThe custom STL file I loaded has emmett's original slits, but I reoriented them so they wouldn't function as intended. It doesn't matter since it cleans up easily and I designed the center pins to be captured anyway.
