Box to hold an LCD screen with four printed buttons on top

thingiverse

The box measures 104 x 64 x 36 mm or 4.1" x 2.5" x 1.4". On the front, a slit is cut where a 16x2 LCD display fits snugly. Built using the rc1602b-ghw-csx LCD display, this unit can be seen at http://www.tme.eu/en/details/rc1602b-c/lcd-alphanumeric-displays/raystar-optronics/rc1602b-ghw-csx/. The slit measures 72 x 26 mm or 2.8" x 1.0", accommodating most 16x2 LCD displays, such as the DigiKey model http://www.digikey.nl/product-detail/en/newhaven-display-intl/NHD-0216BZ-FL-YBW/NHD-0216BZ-FL-YBW-ND/1701195. On top of the box, four buttons can be placed, which can also be printed. Inside, space is available for four micro push buttons on a standard PCB, held in place with five screws through holes. Nigini Tact-67N-F microswitches were used; see http://www.tme.eu/en/details/tact-67n-f/microswitches-tact-pcb/ninigi/. The last STL file contains the cover, with an additional hole for an external wire. The box was utilized to create a simple alarm clock using an Atmel AVR micro-cpu. However, it can be employed for any electronics requiring information display and basic button usage. Print Settings Rafts: No Supports: Yes Resolution: 0.3mm Infill: 10% Notes: Supports are necessary for the box to print the square holes holding the buttons; other models do not need supports.
