Thanks for your help. I loaded the ldd files and added the wheel (minus the metal axle).

I try to use the wheel2a and wheel2b in Bricklink Studio. These are the old spoked LEGO train wheels, available in the Development Version 20210710, the files are 24300 and 24400), but both models are marked as "nullbrick" when I open the appropriate 210710.lxf. Is there anything I can do about it to use those wheels? I looked around a bit but couldn't find a solution for that problem.

Thanks, but that‘s not really what I was looking for. I’d like to try and print the original design of the old big 7750 wheels in 80s style and check if those printed wheels are a good solution for daily use.

Hi there, does anybody know of 3D print files for printing the big train wheels of a Lego 7750 - especially for using them with a standard technic axle? I've searched a lot but couldn't find any 3D files for these wheels. Regards, Anna
