Got mine printed by PCBWay, and as you can see in the pictures they're a perfect fit for the original!
Files are available for free to print for yourself, however if you want to order them, please consider using the PCBWay Shared Project instead (this gives me a donation of the sales in return, so I can order more verification prints like these in the future!).
UPDATE
Added a extended front shell (TopExtended variant), so you can get a big (custom) label made.
Additionally a version was added which should be compatible with MegaDrive/Genesis PCB's, this is however not tested yet, so I can't promise it will work.
The author marked this model as their own original creation.
