Handwheel

[clio 0]

I have made a simple handwheel in Sketchup with in the middle a square of 6 mm when I export it and import it in Cura I still see the square however when I slice the handwheel then I do not see the square anymore and when printed I just have a solid disk (50 mm diam and 9mm high) ps the square is 6mm.

Is it useful to run it trough netfabb or meshfixer before import it to Cura??

I want to have it solid although I also tried with 20% infill.

Is the square water tight? In the cura expert settings you can also play with fix horrible a and b and check if that solves the issue. Looking at the layers in Cura you can see what it will do. If the square can not be found in layer view then it is no use printing it.

I had a similar problem a while back when trying to print a metric threaded hex nut and bolt. The bolt came out fine but the central hole in the nut got filled in. The solution was to turn off the "fix horrible" features. If your 3D design tool creates proper watertight models then these fix features are not needed. Unfortunately, SketchUp is one of those that often fails to create watertight models, but you can download a plugin (Solid Inspector) that checks your shapes for correctness.
