Bench Power Supply

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,
