Super hack to create hollow objects for 3d printing in Rhino

This is a quite easy “hack” how to create hollow objects that are usually not allowed by other CAD programs. Great for 3d printing. Simply connect the outer and inner objects via some random pipe or box, then join everything and untrim the hole that connects them with the ! _Untrim tool. You will notice that the two original separate objects now appear as a single object instead, despite the lack of an actual connection in-between. An alternative way is to select both objects and use the following commands: NonManifoldMerge, then CreateRegions, then delete the region you do not want, such like the core inside the sphere in this particular example.

Make the top surfaces of your 3D prints (almost) perfectly smooth with Cura “Ironing” setting

o you want to improve the quality of yours 3d printed Parts. the “Ironing” setting can help you get smooth surface of your 3d printes.. The setting can tremendously help with the topmost layer surface finish when printing objects with big flat areas on top (in my test case, it was a keychain I was making for a friend). For “curved” objects it should not matter. Here’s how it works: when the topmost layer is finished, it REPEATS it without moving the print head higher. The head moves in a more dense zig-zag pattern (customizable, default 0.1mm) with much lower extrusion multiplier – not sure if it was 5% or 10% by default, but in my test case I used 10%, and it worked flawlessly. This helps smooth out any surface irregularities and gaps on the topmost layer, hence the name: “ironing”.
