Original CAD files (not DXF)

Hello there.
As this is an open source project, please could Precious Plastic upload the original CAD files containing all the original parts so that people can edit the parts directly in the CAD program? For example if we wanted to render it with a different hopper, or print some of the parts on a 3D printer instead of making them out of metal, it would help massively if we didn’t have to make the CAD files from scratch. I am talking about the CAD files for the shredder as there are no actual CAD files in the zip file (I’m not talking about the DXF files, I’m talking about the CAD model of the machine and its original parts). Please could you upload the full set of CAD files for the shredder (and the other machines)?

The actual CAD files are in fact in the zip file…

Use the command “explodeblock” in Rhino on the assembly. Then you can manipulate individual pieces.

I had asked what CAD package you managed to use for editing the CAD files and you said Rhino @siemenc
What I asked for originally was the original CAD files with all the parts, so that each part can be modified individually. I can only open what seems to be an assembled model, but the parts are not included. How could I manipulate individual parts separately, for example just the hopper or just the motor, if there are no individual files for each part? Some of the original parts files seem to be missing.

I saw the folder but I had expected that there would be multiple files for all the parts and thought the .step, .iges, .sat, .smt files were different files associated with the same program as the .f3d file (when I Googled f3d, it came up as “Fusion 3D” so I thought I needed to download a program called “Fusion 3D” and not “Autodesk Fusion 360”). Why don’t they add in a ReadMe file just to explain what programs each file extension is associated with? I didn’t recognise any of the file extensions so it would really have helped if there had been a ReadMe to explain what they are.

In the zip file in the folder:
precious-plastic-master > 3. Build > Shredder > CAD files
you will find all types of files (.step, .iges, .sat, .smt) that should be complementary with most CAD software. I used Rhino to open it. The f3d file is for opening in Fusion 360 which is a free software for hobbyists and small-scale businesses.

Only f3d files, which I can’t open… What CAD package do you use to edit them?
