Converting PCBs and FR4 plates GLB files to STL/Step
Hi everyone, I want to convert the GLB files downloaded from the Typeractive wireless corne builder to STL or - even better - STEP files to be used in Fusion 360 to design a 3D custom printed case.
I tried using Blender and exporting the objects to STL. However, when importing into Fusion360, the scale is off (shows the PCB thickness as 0.14mm). Also, using mesh/STLs within Fusion360 is not the best experience. I followed several tutorials and directions from ChatGPT to convert this STL into a solid in F360, but no matter what I try, F360 becomes unresponsive when trying to Convert the Mesh to a solid. Also, the imported mesh (STL) in Fusion360 shows several warnings (mesh not closed, mesh not oriented, mesh doesn't have a positve volume), which leads me to think it's a problem with the expored file in blender.
Any help will be greatly appreciated.

Hi there!
It sounds like you're running into some scaling and mesh issues when converting the GLB files from our Corne Wireless builder for use in Fusion 360.
The scaling issue might be related to the units used in Blender during export. Ensure your Blender scene units are set to millimeters before exporting to STL. When importing to Fusion 360, double-check that the units are also set to millimeters to maintain the correct scale.
Unfortunately, I don't have any information on converting the GLB files to STEP files.
For the mesh issues, try using Blender's "Remesh" modifier before exporting. This can help create a cleaner, more uniform mesh that Fusion 360 might handle better. Also, in Blender, try using the "Make Manifold" tool (under Mesh > Clean Up) to fix non-manifold geometry before exporting.
If you're still having trouble, feel free to reply or tag me for further assistance!
I tried this, but Blender becomes unresponsive when applying one of the modifyiers listed above.
using Blender's REmesh makes it unresponsive. Could you indicate what steps should be followed to export from GLB to STL. When attempting to do it in blender, I get several warnings after importing in Fusion 360: Mesh not close, mesh does not have positive volume.
