Description

Teaching aid for learning to read and write braille with large 6mm diameter dots.

https://youtu.be/Z9aghYXRcNk

Customization

Case Size

Single cell
8-cell

Case Style

Hard Case with embedded TPU inserts
Fully TPU Case

Button Options

Flat
Round

Printing

All parts can be printed without supports
Cases are printed upside down (walls facing up) so there is no bridging
92A durometer or softer TPU is recommended for all flexible parts
Print buttons in PLA or other rigid material
If printing the hard case on a multi-material printer, turn on “Interface Shells” so the - TPU gasket has a solid base to print on
If printing the hard case on a single-material printer, pause the print just before the layer where the case begins to bridge. Insert the TPU gasket so that the top is entirely flush
2 perimeter walls is sufficient for all flexible parts, but additional perimeters may provide better results if the buttons feel too loose

Assembly

Press fit buttons into the case.
That's it!

This is so awesome of you to make, and public domain at that. I wish the best for you and your future, you are awesome.

Thanks so much :)

absolutely love the design and the idea behind it! I was wondering if you could adapt the cells for 8 dots per cell, as there is an 8 dot standard for working with braille displays for computers.

Great idea!

I've included STEP files in the project so it can be modified easily, but you can actually create an 8-dot version using only your slicer. Just split the the cell into 2 halves so that one half has 4 dots per cell. Delete the scrap half and duplicate the remaining larger piece. You can then rotate that copy and merge it back together :)

I hope I explained that clearly enough.

For easier alignment, here are the grids used for both sizes: 6mm dots - 10mm grid 4.5mm dots - 7.5mm grid

I congratulate and commend you on this design and they way you're sharing it with everybody!

I don't know if this could be a good idea, but could you add a small nipple on one of the short sides so whenever a blind person takes one of these in their hands with the buttons already raised, they will know which side is up?

I failed to mention it in the video, but one side of the cell has a vertical line carved into it for that exact purpose :)
