Soda Can Crusher V2

to make it less confusing, I just uploaded canCrusherV26.scad, and the 2 library files rack_and_pinion and simplethreads and regenerated all of the STL files for the different parts, and labelled them all as V26.
For my slicer I use simplify3d. It does report some small problems on the threads for the arms but this is in the library so I am not sure how to fix it. I had no problems printing it with those minor errors.

I will repeat: there is a lot of force required to crush a can, particularly in the bottom piece. I recommend 50% infill and 3,4 or 5 outer layers. Each peice will take a long time to print as in many hours. It was designed to fit on a flashforge creator pro, which is not a small print bed, but it is much smaller than some of the newer printers. The shorter handles were included so that it might fit on a smaller print bed. The orientation of the parts makes a big difference, and supports are needed.

The openscad source file was included so that people could make minor mods to fit a different print bed.

==================

I just updated a slightly upgraded version.

Well it was time to revisit one of my most popular 3D print creations!
This addresses a few concerns expressed by Thingiverse readers in the comments.

1. the handle is now split into 2 pieces which makes it much easier to print, they still need support, but they can be printed with the gears flat.
2. No metal bearings. All you need to do is use a little lubricant, like Vaseline
3. length of the handle. I found that I could now print the handle 5 mm longer than before because of the re-orientation, but I also included one 10 mm shorter for smaller printers.

I kept all of the teeth on the gears because I think they look cool
I had a lot of trouble getting the threads to line up on the handle, so I am not sure if this is printer dependent or not. Please check it out.
