Sudoku Puzzle

I wanted an alternative to printing 4 x sudoku games on A4 paper.  My older eyes were also struggling with small fonts, so I designed this sudoku game to be about the same size as my Android tablet (134 x 225mm).

Above the puzzle area is a storage area for the numbers.  This has the benefit of showing which numbers are already completed in the puzzle, and which ones are lagging.

I printed the parts in PLA with a manual colour change to make the puzzle border and the numbers stand out.  The numbers slide into the storage slots more easily if given a slight twist (about 30 degrees CW or CCW).  They have clips to hold them in the board, not super securely but enough so that the board can be tilted.

I used PrusaSlicer to add the text to the numbers and am really happy with the stencil font.  You can change this in the 3mf files if you prefer a different font.  The 6 has an extra dot to differentiate it from the 9.  I exported the numbers with text as stl files so you can print spare numbers if you lose one in your bed or sofa!

I hope you enjoy!
