2. Move QuickLookSTEP.app to /Applications
3. Open the app once to register the QuickLook extensions
4. Now press Space on any .step or .stp file in Finder

Note: Since the app is ad-hoc signed (not notarized), macOS will block it on first launch. Right-click the app → Open, then click Open in the dialog to allow it. If that doesn't work, navigate to Settings > Privacy & Security > Security, click "Open Anyway".
