Summary
Fittle is an accessible learning toolset for visually challenged kids, in the form of a playful puzzle. By feeling braille letters embossed on the word blocks, and then feeling the shape that s/he has fit together, the kid can touch what the object might feel like in real. We are currently testing the beta version. Go ahead. Download your first Fittle (v.1.0.4)

Instructions
All the 4 files in the zip folder can be printed at once on a 3d printer with at least 10cm x 10cm x 10cm printing area. Make sure that the height of each block is 2.2cm when it is aligned in the printing software so that the braille side is facing up. If not, calculate the relative percentage and scale it down to 2.2cm height.
Best printed in ABS. Try to scrape off the support material while fresh off the printer. Try not to touch the braille dots till it has cooled off completely.
