You may not find that exact model but many stl files available on thingiverse.com and they are simple to convert.

[rmachinist]

hmm how do one convert the stl file?

[rmachinist]

gibbs can't open stl file

[Louis_Cannell]

Try Freecad import .stl and export to .iges format I believe thats a format compatable with gibbs

Those wood models are carved on at least a router with at least 4 axis. You can do it on a 3 axis router if you have a good fixture setup and rotate/re-mount the model for each face. That may be how these were made considering the price they are asking. Using a 3d printer would be fairly simple if you wanted it out of plastic, but I thought the pinewood derby cars were supposed to be wood? They do make wood based PLA for 3d printers! So much for the kids building it and carving the car themselves using creativity...

I downloaded free cad try the .stl export to .iges, the .stl file loaded up right in free cad when I exported to iges file then opened in Gibbs I get a blank screen any idea?

Try converting mesh to a part from memory start to complete then Part : create part from mesh before exporting

I think I’m real close on getting this to work, first of all I want to thanks you Louis for helping me so far, I don't know free cad that well when you say: mesh to a part from memory start to complete then Part: create part from mesh before exporting. I don't understand how or what to do on this freecad to can you go step with me on this?

[rmachinist]

Louis after playing around I got it to load up on Gibbs!!! Thanks you! Now I have another problem how can I mill it in 3d?

[Louis_Cannell]

Start and complete are on a drop down menu when editing
then Part will be a menu item
then create part from mesh an option under that

[Louis_Cannell]

Use a 4 or 5 axis mill, or mill one side at a time on a 3 axis mounting/clamping it very accurately each time.

I been playing around with this in Gibbs now, do I need to surface modeling or something like this?
