Raspberry Pi 5 Inch car stereo unit

thingiverse

This is the result of a month-long pursuit to create my own stereo head unit for my car. It utilizes a Raspberry Pi with a DAC, a 5-inch LCD from Waveshare, an IQAudio Cosmic Controller, along with an Arduino Pro Mini to interface with the Pi and provide power control. There are two versions of the STL: one for using an SD card extender towards the back, and one that eliminates the SD card and uses an SSD instead, moving the Pi up by 4mm. This is not a 2DIN ISO 7736, it falls one centimeter short. My car features a 180x90mm slot, not 180x100.3mm, which is part of the reason I decided to build my own unit. If you are familiar with Designspark Mechanical, you can probably adjust this with some work. It is split into parts no longer than 120mm in length, allowing printing on smaller printers. All parts are assembled using M2.5 nuts and countersunk screws 6mm long, M2.5 screws. The screen uses M3 regular screws and nuts due to the larger holes. The click mechanism employs 7mm by 8mm springs, along with 1.5mm metal rods like a cut-down nail. There is no top: I simply cut and glued some 3mm acrylic, so you can see inside. Only two holes and some glued tabs are needed to hold it in place. If anything, this could provide inspiration on how to create a big functional object with a smaller printer, and how to design and use connection methods.
