Finally after the review , completely redesigned the whole thing , made the pcb smaller ,made the 3d box smaller too . Also estimated the price in jlcpcb to get the pcb its hella 3.51$‘s now i think i need to write firmware but before tht i havent made any holes on the cad’s mounting portion(i mean where the pcb and the esp is screwed), after i get it in hannd , i ma gonna do tht manually , it will be more helpful .
