Modular Magnetic PCB Holder for Makers

Create a clean, flexible PCB workholding setup with this modular magnetic fixture system. Start with two holders for smaller boards, then print additional modules to support larger PCBs and more advanced custom layouts. This makes it a practical, low-cost alternative to expensive PCB fixture systems on the market. For makers, it offers a clean and highly flexible solution that is easy to expand as your projects grow, while using less than 25 grams of filament per unit with very little waste. The magnetic design lets you quickly position, move, and fine-tune each fixture on a ferromagnetic base plate, making it ideal for soldering, testing, prototyping, and assembly. I used an old build plate but any piece of ferromagnetic metal will work! Each module uses 1× M3x18 screw, 3× 4x2 mm magnets, and 1× M3x5x4 heat insert. You can complete the system with either a printed spring or a metal compression spring, depending on your preference. Spring options: Printed spring generator: https://make
