18650 Battery Holder
Print Profile(2)
Description
I need to use Li-Ion battery for my new model Gridfinity Bluetooth Speaker but only had the 18650 on hand. Used YXC's design as a reference to build my own battery holder.
It is a print-in-place design that requires no additional metal planes or springs. Simply insert the wires directly into the holder and you're done. It also perfectly fits both standard and protected 18650 battery.
Although my print profile is with PLA, using PETG is recommended for greater flexibility and durability
Two version is created. One is the standard version with 3mm wall, the other is the slim version that can be put into a 2x1 Gridfinity bin
You can also download the holder for other sizes (21700, 18650, 15400, AA, AAA) from below:
