Bracket to mount Raspberry Pi to Ender 3 printer

thingiverse

Here is a bracket designed specifically to accommodate a "bareback" Raspberry Pi (version 2 or version 3) on an Ender 3 frame. To secure the Pi, use size No. 2 * 1/4" Pozi Pan self-tapping screws available from eBay. Next, utilize M4 bolts and nuts that come as spares in the Ender 3 kit to position the bracket exactly where you need it. On the underside of this bracket are standoffs engineered to hold an LM2596S Buck Converter sourced from https://bit.ly/2NtCTdP. This converter takes 24 volts from the power supply unit and efficiently converts it into 5 volts at a rate of 3 amperes to power the Raspberry Pi.
