Alimentation laboratoire ATX (Lab/Bench Power Supply based on ATX) - Dual USB Facade Update.

Hi All,

The first project I built back in 1990 when I graduated with a BS in Comp-Eng was a power supply.  It has served me well all these years, but it was limited.  So I decided on a new 3D printed update.  I like Sebr's power supply design and I built it for myself.  However the square hole for the dual USB port on the face plate was excluded from the final published files.  So I decided to add that back because I liked the idea of having a few 5V USB ports since many of my designs use USB powered boards like the Wemos D1.   

I have included both the Faceplate with the USB cutout for a 14.5 mm x 15.25 mm dual USB port and the carrier to hold the PCB and USB ports.   See pics for some detail.  Per Sebr's instructions, you will need to program a color change at around 2.8 mm for the text on the facade.    I like using machine screws for 3D printed designs, so I tapped the facade mounting holes and USB carrier with 2 mm threads.

Also you will need some protoboard.  About 20mm x 20mm with 100 mil holes.
I used these: https://www.amazon.com/dp/B01N3161JP?ref_=cm_sw_r_cp_ud_dp_FBAJ24A7DND97ADNPF0Q

And dual USB ports.  You can cut off the mounting tabs because the carrier will hold the ports secure enough to the facade.  https://www.amazon.com/gp/product/B07L3M98V1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Lastly, I revised the base rails to have a small 10mm detent for rubber feet so that they better stay in place.

Enjoy, this was a fun / useful project.  Thanks Sebr.
