retro pi system

i made a retro pi game console and thought ide throw up the model for anyone that wants it.it fits a pi 1b and i made a custom button layout that fits on the mounting screws and as for the power for the pi i used discarded vape batteries from friends and family which fit under the key pad. there is a switch on the right hand side which cuts power to the pi to turn it on and off' had to use a boost converter to boost the power from the cells to 5v and i used a basic lithium battery charger module to charge the batteries .there is also a port for direct access to powering the pie for trouble shooting . as for a display i used a cheap 1.6 inch display( 240x240 SPI Interface ST7789 )
the system has holes in the sides for access to the usb, network and audio ports as well as the sd card. the one case version also provides the option for mounting a fan
