This is a design of a front panel for a DIY Bench Power Supply from a computer power supply. The instructables is: http://www.instructables.com/id/Diy-Bench-Power-Supply-3D-Printed/ . It doesn't need to be screwed on as I found the fit to be quite tight, But there are holes anyway. Be careful when working with electronics! Designed with Autodesk 123D. If you want me to upload the design files just let me know. All feed back is appreciated :) I'm always open to suggestions on how I could improve, and I would love to see anyone else who made it too.1) Print all parts on the printer of your choice. 2) Put two pieces together, ensuring you insert the pins with a dab of superglue (Cyanoacrylate or similar). 3) Insert components to corresponding holes. 4) Solder wires onto binding posts, LEDs and switches. Test to ensure it works! 5) Push front panel onto power supply, Give it a bit of force as I found it was a tight fit. 6) Use screws to secure if necessary. 7) Power up and test your build.
