Bigger case for motion activated led lamp to fit 18650 battery

This is a bigger case for a LED lamp with PIR sensor from Aliexpress. It fits one or two 18650 batteries. 

There are multiple versions of this lamp on Aliexpress. I have two of them:

1. With switch labels “ON AUTO OFF”. This version has R2,R3 resistors that set the time delay. I changed R3 from 150k to 270k to increase off delay from 22sec to roughly 2min.
2. With switch labels “OFF AUTO ON”. I couldn't find a way to adjust the time delay.

This case fits both versions. Two STLs provided with different switch labels. 

The plastic switch is reused from the original case. 

The case can be printed with fuzzy skin to give it some texture. To apply fuzzy skin to only the outer layer the STL modifier is included. 

The charging current is set with R11(ON AUTO OFF ver) or R1(OFF AUTO ON ver) to 100mA and can be increased up to 500mA but the IC will heat up quite substantially.

The case contains places to put three neodymium magnets (6mm x 3mm). I press fitted mine without any glue. Three magnets hold fine the lamp with a single 18650 cell on a horizontal surface.

I printed mine from ABS with 0.2 layer height without supports. 

Fuzzy skin settings: thickness 0.2, distance 0.4
