Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on pcbway.com ➠ ➠ ➠Over the years, I’ve designed a set of under-shelf test modules that have become essential to my electronics restoration and repair work. Many of you have asked how you can build your own — so I’ve finally created a standardised module system that you can 3D print and customise yourself.
In this video, I walk through how I created the new modular enclosure, which fits neatly under a typical workbench shelf, and how I’m converting one of my existing modules to this new format. I also share:
🔹 Fusion 360 source file
🔹 3D print STL files
🔹 Artwork design file
🔹 Direct link to order the #D prints from PCBWay
Whether you’re building your own capacitor tester, Dummy Load, or RF Attenuator module — this system is meant to be flexible, functional, and free to use.

▶ Order PCB directly (optional): [🔗 pcbway.com/project/shareproject/EO_N_Under_Shelf_Module_for_Electronics_Test_Gear_e9635e47.html]
I don’t sell anything myself — this is just a personal project I’m happy to share with the community. If you end up building one, I’d love to hear about it in the comments!
