<p>Hi All,</p><p>The first project I built back in 1990 when I graduated with a BS in Comp-Eng was a power supply. &nbsp;It has served me well all these years, but it was limited. &nbsp;So I decided on a new 3D printed update. &nbsp;I like Sebr's power supply design and I built it for myself. &nbsp;However the square hole for the dual USB port on the face plate was excluded from the final published files. &nbsp;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. &nbsp;&nbsp;</p><p>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. &nbsp; See pics for some detail. &nbsp;Per Sebr's instructions, you will need to program a color change at around 2.8 mm for the text on the facade. &nbsp; &nbsp;I like using machine screws for 3D printed designs, so I tapped the facade mounting holes and USB carrier with 2 mm threads.</p><p>Also you will need some protoboard. &nbsp;About 20mm x 20mm with 100 mil holes.<br>I used these: <a href="https://www.amazon.com/dp/B01N3161JP?ref_=cm_sw_r_cp_ud_dp_FBAJ24A7DND97ADNPF0Q">https://www.amazon.com/dp/B01N3161JP?ref_=cm_sw_r_cp_ud_dp_FBAJ24A7DND97ADNPF0Q</a></p><p>And dual USB ports. &nbsp;You can cut off the mounting tabs because the carrier will hold the ports secure enough to the facade. &nbsp;<a href="https://www.amazon.com/gp/product/B07L3M98V1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&amp;psc=1">https://www.amazon.com/gp/product/B07L3M98V1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&amp;psc=1</a></p><p>Lastly, I revised the base rails to have a small 10mm detent for rubber feet so that they better stay in place.</p><p>Enjoy, this was a fun / useful project. &nbsp;Thanks Sebr.</p><p>-Jeff</p><p>&nbsp;</p><p>&nbsp; &nbsp;&nbsp;</p>
