Mathematics should be accessible to everyone. This is a fully 3D-printable Braille Multiplication Table designed to help visually impaired individuals seamlessly learn and practice multiplication (from 1x1 up to 10x10) through touch.
Carefully designed with ergonomics in mind, this board ensures a fluid, frustration-free reading experience.
Key Design Features:
Optimized Dimensions: The board measures 197 x 125 x 9 mm, providing a spacious yet portable layout that fits comfortably on a desk while remaining easy to handle.
Clear Tactile Grid: Features distinct recessed grooves separating each cell, making it easy for the fingers to navigate and track rows and columns without losing place.
Dual-Level Navigation: The row and column headers are elevated (+1mm) compared to the main multiplication results (Level 0). This subtle height difference provides immediate tactile feedback, distinguishing the factors from the product.
Optimized Braille Dots: The dots are perfectly proportioned (1.60mm diameter, 0.90mm height) with a smooth, rounded fillet to ensure they are comfortable to read and not sharp to the touch.
Important Print Settings (Included in the 3MF):
To ensure the Braille dots are perfectly smooth and readable, the slicing profile has been highly optimized.
The print takes approximately 5.5 hours and prioritizes extreme tactile quality over speed.
If you are using your own settings, please follow these guidelines:
6 Walls / Top Shell Layers: This is crucial! Using at least 6 walls/top layers ensures that the spherical top of every single Braille dot is printed perfectly solid and closed, with no micro-holes or weak spots.
Adaptive Layer Height: The base is printed at 0.12mm, but Adaptive Layer Height is active. This drops the layer height down to 0.04mm specifically at the tips of the Braille dots, turning them into perfectly smooth domes without harsh "stair-stepping" effects.
Arachne Wall Generator: Strictly required to accurately generate the tiny 1.6mm perimeters of the dots.
Scarf Joint Seams: Enabled and set to "Back" alignment. This eliminates the classic "seam bump" or zit on the side of the dots, ensuring a flawless reading experience that won't scratch the fingertips.
