Hacked off the charger from https://www.thingiverse.com/thing:2892321 and then shoved 3 together and cleaned it up a little, just a little ;) Then added a platform for those trashy $1 bms for 3s, wired it all up w/ some 24ga rj45 wire, double sided tape to the platform and a ziptie for good measure and its fine.
I would NOT recommend using the FAKE 500mah 18650s or trashy $1 BMS you see me using, I just have so many im trying to find ways to use them in .5-1amp applications.
If u want to use a real bms with this you should edit the platform around to match it.
