Black Widow Spider for Halloween

This 3D printed flexible Black Widow spider is printed from Black and Red NinjaFlex. The flexible legs dangle and wiggle when lowered from a string. There are two holes, where red LEDs can be inserted in from the bottom. The red LED's cause the translucent red NinjaFlex to glow with an eerie look. Printed at this scale, it is 10cm across the legs
The 2 red LEDs are wired in series and are connected directly to a 3.7 LiPo battery. So far almost 48 hrs from a single 18650 battery.

Note: If you print with the NinjaFlex directly on clean glass, the spiders will stick directly on a window, similar to those vinyl reusable stickers.
