How to Design a 3D Printable Puzzle in Blender (Bezier Curve Trick)

In this tutorial, I show you how to design a 3D printable puzzle in Blender using a simple and flexible workflow based on Bezier curves and boolean modifiers. We start by creating puzzle shapes using curves, convert them to mesh, and then use them to cut clean puzzle pieces from a base object. Finally, we design a tray so everything fits together neatly. TIME STAMPS: 00:00 - Intro 00:35 - setting up the puzzle base 02:11 - Adding Bezier curves 03:33 - refining the curves into puzzle pieces 11:24 - Converting the curves into a mesh 15:39 - making the base 17:25 - Outro In this video, we cover: • Creating puzzle shapes using Bezier curves • Converting curves to mesh • Adding thickness with the Solidify modifier • Using the Boolean modifier to cut puzzle pieces • Designing a base and tray for the puzzle • How to scale the design to more complex puzzles This example uses a 4x4 puzzle, but the same method can be used to create puzzles of any size or complexity! This is a great project for learning how to combine: curves modifiers boolean workflows print-ready design If you're learning Blender for 3D printing, this is a fun and practical way to build your skills. I post weekly tutorials focused on functional 3D prints and tabletop designs.
