I am at a loss here and kindly ask for help: I designed an ice scraper with SketchUp by drawing the outline and then pushing it to a width of 99mm. I then added curved lines on the surface using the push/pull tool’s “new starting faces” (Option key on MacOS) feature to create kind of handles to get a better grip.
When I export this model to STL and try to slice with either Cura or Slic3r everything looks garbled. I have holes and a plethora of missing layers (in layer view).
Using makeprintable.com I could get a fixed STL that slices nicely. But I would very much prefer to design models in SketchUp that correctly slice in Cura.
The *.skp might help: It can be downloaded here http://zeropage.io/download/Eiskratzergriff14.skp
What is wrong with my model? What is missing?
Your help is kindly appreciated!
Many thanks in advance
