Pre-loaded 3-D Builder Software no longer available in windows 11

Hello everyone.

I had been using the 3-D Builder Software that came preloaded in Windows (prior to Windows 11) to repair the jewellery models before I print them. This software worked excellent and was simple to use.

I now have windows 11 and the 3-D Builder software is no longer pre-load or available to download on windows 11.

Looking for advice as to the best easy to use free 3-D builder software to repair models.

Thank you for your input:)

what type of models and what type of repair?

Meshmixer is free, it can do some repairs, but if the mesh is very bad it may not be able to fix it.
