Grabcad is a good resource. For parts that are highly standardized you can find a library for all DIP ICs, Pin headers, TO-220 etc. For stuff like capacitors there are so many sizes that it is unlikely to find an exact match at grabcad. Source: 7 months ago

You're not very likely to find an STL file, but it would be easy to find a STEP file which any decent CAD program could convert to STL. Take a look on https://grabcad.com/library. Source: about 1 year ago

Ok some things here. Stl does not works well with fusion360, you'd be better off modifying it with blender check this video) If you want to use fusion try to find a similar file in STEP format or IGES the best place to find it from is Grabcad. If you really want to import your stl into fusion 360 here is the way to do it properly And to finish up you NEED to give more info to get help, I know you're scared someone...

If you're looking for CAD models I use https://grabcad.com/library. Source: over 1 year ago

You don't sell on there, that website is to share your designs with others for free, you can sell your files on cults, here is a link to their website https://cults3d.com/en. Source: about 1 year ago

Some folks have found success selling just models with sites like cults3d and my minifactory too. Source: about 1 year ago

Just https://cults3d.com/en or any site with files tbh and search "Blood Bowl Scatter". Source: about 1 year ago

There's also MyMiniFactory, not to mention Cults3D. Source: over 1 year ago

I know StationForge just put up some models that could be used as proxies. Quite a few if you browse https://www.myminifactory.com/. If you are looking for free proxies, MyMini has some usually, but https://cults3d.com/en tends to have more options. Source: over 1 year ago
