3D Printing file expand center hole and rotate 45 degrees

Job ID: 34418315

Budget: $10 – $30 AUD

Hi,
Given the STL/STEP file I've uploaded, I need two changes:
- The center hole needs to be expanded to a square measuring 5mm x 5mm
- The center hole needs to be rotated 45 degrees from where it currently is.

I've attached an image describing the current design and how it needs to change.

Thanks
