Raspberry2+4Relay+Fan(Octoprint)

This is a raspberry model 2 b with a 4 relay to turn on my printer remotly and of course turning it of after print. It has a personal design on the top but you can just take it of jejejje
It works perfectly, the only problem might be the conector between the raspberry and the relay must be short , if not it wont fit to close (awful english i know but i m trying ;D)
i atach the fusion 360 file for changes and remixes
