A 3D-printable replacement I/O shield for the MSI B450M Mortar motherboard.

Designed to replace the original rear I/O shield if it is missing, damaged or lost.

The model is designed to fit the motherboard's rear connectors and the standard PC case I/O opening.

Printing

  • Layer height: 0.20 mm

  • 2–3 perimeters

  • 15–20% infill

  • Print flat

  • No supports required

  • PLA or PETG recommended

Compatibility

Designed specifically for the MSI B450M Mortar.

Compatibility note: This I/O shield was designed and physically tested on the MSI B450M Mortar.

Based on MSI's official datasheets, the MSI B450M Mortar MAX and MSI B450M Mortar Titanium appear to share the exact same rear I/O port layout (same port types, order, and positions), so this shield should also fit those two boards — however, I have only physically verified it on the standard Mortar. Print and fit at your own discretion if you're using it on the MAX or Titanium variant, and feel free to leave a comment confirming fit if you try it!

If you print it, I'd appreciate a photo of your result and any feedback about the fit.
