## Design Concept This 3D model represents the number 'four' in Braille code, ideal for assisting in tactile learning for the visually impaired. ## Purpose It serves as a tactile educational tool intended for classrooms or personal use to teach and familiarize students with Braille numerals. ## Printing Recommendations Utilize a standard PLA filament with a layer height of 0.1mm for smoother tactile surfaces. Ensure the printer bed is properly leveled to avoid misprints. ## Assembly Instructions No assembly required. After printing, check the surface for smoothness to ensure it is touch-friendly and comprehensible for Braille readers.
