3D Printing Design Principles Model Set

This model set helps you understand the core principles of designing for FFF 3D printing through simple, physical examples. Each cube demonstrates a key concept, showing how design decisions affect printability, strength, and surface quality. Instead of only reading about these ideas, you can see and feel how they behave in real prints. The set is designed to be used alongside the included Design Principles Guide, which explains each concept with clear visuals and practical rules of thumb. Key principles Each model represents a key design principle: Overhangs Bridging Minimum features Orientation Fillets Chamfers Tolerance Holes Sharp points Together, they provide a foundation for designing parts that print reliably and efficiently. Printing Print using standard PLA material and slicer settings (0.2mm layer height, infill 15%, no supports). The goal isn’t perfect prints, but to observe how each feature behaves under typical conditions - small imperfections are expected. You can print t
