Short edges for export as 1:1 scale

Hello,

How do I create 3D volumes for export as 1:1 scale DXF files for outsourced manufacturing while avoiding “short edges” on features like 2.5mm holes?

The “Solid Inspector2” plugin is flagging an error.
« Small geometry might cause unpredictable results due to precision errors. It’s beneficial to try to avoid such small geometry. This cannot be automatically fixed. You might want to scale the model up by factors of 10 to work around such problems. »

Thanks for your help
