mini buck converter box

mini buck converter box i made for my ender 3 pro. i have direct drive on mine and i have a noctura hot end fan and hero me gen 5 part cooling fan with the dual 5015 blowers so i needed to install some buck converters. i wanted something small, easy and easy to get to. that being the case i had the bracket where my old extruder motor use to be in and my wires for the fan go right by it so i made this buck box to fit right where the stock extruder goes it has the same bolt pattern and the nema17 stepper motor. obviously this wont work for you if you are not direct drive however. i used these buck converters. you can get them cheaper elsewhere but amazon links will likely be longer lasting than a ebay link or so on.
