2x18650 batteries power pack

thingiverse

I needed a powerpack to add to one of my robots, I already had the batteries and the board and decided to tinker something in Tinkercad during the weekend. The tolerances fit my printer, the board needs to be fitted using a small scre driver to force it carefully under the clip and 3mm screws are used for battery contacts. Important: This design is made for flat top batteries which fit very tight. If you have different 18650 you need a longer box so you have to even modify the stls to fit the batteries even replace the screws with other means of getting a good electrical contact.
