I'm quite new to blender/modelling, and though I have made a few successful pieces previously, I'm having an issue in generating an object for 3d printing.
Here, I've thrown this together by extruding the points up, creating faces an then insetting them, but the icon doesn't really have any physical volume, as it has no inner side wall or bottom face. Plus, the lines are all inset, instead of being equal on both sides of the line I really need to make it so that the lines all basically have a square tube around them all.
I've heard of people using bezier curves, and then beveling the lines to add thickness. This gives me several issues.
Finally, the corners of the shape have open ends, and I'm hoping to make it so that the object has sharp corners.
Any help with this issue would be much appreciated.
