crankk pin
I changed all pins from 4 mm diameter to 5 mm. 4 mm would be fine for good printers and if you are knowing what you are doing but I want to make it fool proof...

Because I came back to my printer after 6 month and I was using new filament I had to play a little with all the settings. As I started with 3D Printing I was using Skeinforge a lot because of it's possibilities to fine tune everything - maybe a problem of German Engineers ;-) For easy printing I gave Slic3r a chance. But with this fine structures Slic3r had a problem. It tends to not following the outer lines exactly and splitting them at random points. Especially with the claws I had some problems to get them stable.

Now I went back to the free KISSlicer. This is a good compromise of nice settings and easy to use operation. Best of all it don't "invent" new outlines like the Slic3r and produces stable print layouts.

Have a look at KISSlicer here. First the support made the crank pin unstable:

By changing the extruson width and the number of loops I got this result:

Printing with this was easy. I am using a nozzle with about 0.45 mm diameter and printed this with 0.5 mm layer height and 0.6 mm extrusion width.
To get this parts stable during printing I used a Z-lift when moving from one pin to the other, a prime pillar and a little fan to cool it.
It came out verry strong. So if people want to print it with 0.25 mm layer height it would come out even better...

As you can see I have to play with the seam positioning and the seam hiding.
