I have a couple solutions that I use: - PrusaSlicer has built-in STL repair, and it has options to save the STL. - MeshLab is open source. A google search such as "Meshlab repair holes" will have you on your way.

- PrusaSlicer has built-in STL repair, and it has options to save the
STL.
- MeshLab is open source.  A google search such as "Meshlab repair
holes" will have you on your way.

Thanks, What I did is used Meshmixer, which cut off the messy part of the model (in terms of shape that I don't want to print and any holes that are present). I then re-added the part of the handle that you hold with your fingers in OpenSCAD and it all rendered well. Thank you, Richard.
