The file 'Card Holder For Playing Cards 3D Printer Model' is (stl) file type, size is 4.0KB.
I made it a bit loose on purpose so it won't be too tight for the different printers.
I made i without support succesfully - but if you want, it is only the small square connecting hole in the end that would need it.
