Wash Out Test Bed

cults3d

I love creating intricate models with multiple components that seamlessly fit together, feature swivel parts or hinges, but they often end up being too bulky and require sanding. Despite seeking advice from experts who suggested reducing 0.2 mm for fit-in parts and 0.4 mm for moving components, I'm still unsure of the precise terminology to describe this process - I simply refer to it as "wash-out size" or reduction. As I pondered this issue, it dawned on me that every printer has its unique level of precision. To address this concern, I designed a test model in FreeCAD using lines of circles and cubes, carefully reducing each step by 0.1 mm to serve as a reference for my future builds. Observe how the circular shape and square shape exhibit distinct sizes for fit-in and swivel parts. Key dimensions for this test bed include: Ring hole diameter: 10 mm Cube hole side: 10 mm While I firmly believe that this wash-out test bed will yield varying results depending on project size, it's possible that smaller or larger projects may require a rebuilt model tailored to their specific needs.
