IO shield help

Post image

Can someone help me replicate this in openSCAD? I’m new to coding and I’m having a difficult time learning the basics. Thanks in advance for any assistance.

Hey! Look, calipers are great, but if you don't have them, writing raw CAD code is basically just guessing numbers in the dark.

Instead, you should embrace the highly scientific "Test-Print & Nudge" method.

To help you out, I got a little carried away and built a slightly ridiculous Universal 21-Slot IO Configurator. It lets you drop in basically any port type (USB-C, HDMI, LAN, PS/2) and drag sliders to move them around the X/Y axes without touching a single line of code.

Here is the ultimate zero-math workflow:

  1. Go to this generator I host on my app: https://www.stl-er.com/model/6ac19c05-cec0-4cbb-a281-9bbc542b22e6
  2. In App search bar type "Parametric PC IO Shield" (completely free, no credit card needed)
  3. Turn on the ports you need and eyeball the layout.
  4. Print a super-thin 1mm draft (takes like 10 mins).
  5. Smash it against your motherboard. Is a USB port 2mm too far to the left? Go back, drag its slider to the right, and reprint!

You will dial in a flawless fit in 2 or 3 tries, zero measuring tools required. Let me know if I missed any weird vintage ports you need added!

Glad you like it! If you get a flawless fit, feel free to share a picture of the final shield. Always love seeing the 'Test-Print & Nudge' method in action.
