Fusion360 is recommened, and Blender for 3D Printing would be harder but not banned, here are some Key Considerations

1. Use Manifold Geometry. Ensure the model is watertight—no holes, loose edges, or non-manifold geometry.
2. Set Correct Units. Set the unit system to Metric and choose millimeters to match most slicers and printers. (Scene Properties > Units)
3. Apply Scale & Transforms. Use Ctrl+A to apply Scale, Rotation, and Location before exporting.
4. Model with Thickness. Avoid zero-thickness surfaces. All parts of your model must have physical volume.
5. Normals Facing Outward Recalculate normals so all faces point outward. (Edit Mode > Select All > Shift+N)
6. Check Wall Thickness. Thin parts may not print well. Minimum recommended wall thickness is usually 0.8mm to 1.2mm, depending on the printer.
7. Avoid Too Much Detail. Overly fine details may not appear well on small prints.
8. Use 3D Print Toolbox Add-on. Enable this built-in add-on: (Edit > Preferences > Add-ons (or Get Extensions) > Search: “3D Print Toolbox”) It helps detect non-manifold edges, intersecting faces, and other print issues. If you could't get it installed, please update your blender to a newer version (4.2+).https://extensions.blender.org/add-ons/print3d-toolbox/
9. Export as STL, and name it use your slack name Use 3D Print Add-ons > Export > STL
10. Check “Selection Only” if you only want to export the active object.
11. Test in Slicer Software， Import the STL into Cura to preview printability and generate G-code
