Prompt

Design a 3D printable handheld Braille reader enclosure. The size must fit comfortably IN a human hand like a TV remote or a thick smartphone — approximately 140mm tall × 75mm wide × 30mm thick. The thickness is intentionally generous to house all internal electronics: 6 LY-011C solenoids, ESP32 DevKit, PCB, MOSFETs, buzzer, and wiring. All corners and edges must be heavily rounded (10mm radius) so a blind user can hold it comfortably for long periods. Two separate shells — front and back — joined by 4 recessed M3 screws at corners. Front shell: Upper center: one single standard Braille cell — exactly 6 pin holes arranged as 2 columns × 3 rows, 2.5mm center-to-center spacing, 1.5mm diameter each. These 6 holes form one unified cell representing one complete Braille character at a time. Surrounded by a slightly recessed rectangular silicone pad zone (30mm × 20mm, 8mm corner radius, 1.5mm deep) Middle: 3 tactile button holes 16mm diameter in a horizontal row (NEXT, PAUSE, BACK) Lower: 1
