It must be printed with 2 gears and 2 screws.

This model is included in "The Fidget Toys Workshop" a complete and practical guide to 3D modeling with FreeCAD 1.02, specifically designed for beginners. This book offers a comprehensive introduction to the powerful, free software FreeCAD, avoiding tedious theory in favor of a fun, hands-on approach. You will embark on a journey to master the essential functions of 3D modeling through the engaging process of creating your own fidget toys.

The learning occurs through the guided creation of 8 fidget toys, each designed as a progressive exercise to introduce new skills. The book starts with the basics, featuring a classic Fidget Spinner, before moving on to more complex challenges such as "Print-in-Place" sliding mechanisms, functional gears, and multi-part assemblies. These exciting models are also available for download on Thingiverse, allowing you to see the final product as you learn.

Throughout these projects, you will master the fundamental workflow of the Part Design workbench: from creating precise and constrained 2D sketches to transforming them into three-dimensional solids. Crucial concepts for 3D printing are also covered, including managing "clearance" for moving parts, creating functional threads, and adopting professional design techniques like the use of a "Master Sketch" to build robust and easily modifiable models. Furthermore, the book offers a glimpse into the power of parametric design by introducing you to the spreadsheet workbench, enabling you to create intelligent and easily customizable designs.

This course is a path that aims to give you a solid foundation in the main functions of FreeCAD for 3D modeling, empowering you to bring your own ideas to life.
