If you upload the broken .stl file to http://cloud.netfabb.com/ it will send you back a repaired .STL file in email. I did this and gear-4 now looks just like it should. I agree that the gear 4 posted here is broken. I would be happy to email this repaired file to anyone who will update this thing.
I tried to print gear 4 and its nothing like the picture. I can't complete the project because the piece is wrong.
So i printed the body parts at 101% scale and I also printed them vertically to prevent the end splitting. So far it looks like this is going to work.
everything printed out way to tight on my Afinia. The u brackets split the frame and the gears fit too tight to turn freely.
How modified are the gears that you make three of?.. Ive already made those from the original. Would those work with the rest of the parts from this?
I made a handle for the handle with
difference(){
cylinder(r=6, h=26);
translate([0,0,26-14]) cylinder(r=4.5, h=14);
}
quite handy :-P
Nice piece! Most of the stls need repairing, maybe you could repair and re-upload?
Had to trim the braces a bit to fit without splitting the sockets but very very nice!
Could you post the SCAD for the brace, gear4, gear4top? Thanks!
Yeah, I just used the original stl files from mraiser. When I get some time I'll use the gear script to make the gears as well because I'd like to add a square output slot on the big gear as well. I tried to do it in openscad by importing his stl unfortunately, his stl has that annoying bad winding order error that openscad can't process. Until then this thing is a work in progress...

In case anyone is curious, I hooked a motor up to this and recorded at 1/8 speed. http://www.youtube.com/watch?v...
