3d printed numbers book
3d print chunky pages for a counting book from 1 to 10. filament swaps would be good for highlighting letters and any printer can do that. pages can be printed in separate parts for front and back and then be glued together.
- a star/back
pages will have bumps to feel on the top, and then the number written out in raised letters below. with a different font it could be brail too.
