I'm trying to print a gear for a robovac deal.

The issue I'm having is with gaps between the walls of the top part of the gear. It needs to have the corners filled to provide stability or else the tabs easily snap. I've tried adjusting the nozzle size, line width, filter gaps and print thin walls but seems to slice with variations on the same issue. Is this a Cura issue? Is there anyway to slice and print this to fill those gaps?

    $\begingroup$ What does the original model look like? It looks like they took a cylinder object and binary subtracted a cube leaving the walls too thin near the corners. This looks like an extremely small part... $\endgroup$

    $\begingroup$ Hello, thanks for the response. I've messed around with it a bunch more today and I believe that the wall is simply too thin on the corners to be printed correctly. I ended up loading the model into blender and extruding the edges along normals to make it thick enough. Once it printed, I threw it on a little spindle and then used a drill and some sand paper to slowly remove material till it fit the bearing it needed to go into but left just enough to connect the edges. The bearing does compress all the sides so I guess it could work even with the little gaps. $\endgroup$ Dec 17 '20 at 2:35

    $\begingroup$ Using smaller line width may work, but Cura has a bug whereby it makes no difference unless you also enable printing outer walls first. $\endgroup$ Dec 17 '20 at 14:39

    $\begingroup$ also, print thin walls can help...or Thickening the area in the model. $\endgroup$
