Black Widow Spider for Halloween
by wozzy, published
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.

I used the following settings in my Mendel 90:
Material: NinjaFlex Flexible TPE Urethane
Color: Black, Red
Extruder temperature: 215C
Bed temperature: OFF
Fan speed: OFF
Layer height: 0.20mm
Solid top layers: 2
Solid bottom layers: 2
Percent infill: 50
Infill pattern: honeycomb
Infill pattern angle: 120deg
It's best to print this at 100% scale, as the legs need to be two layers thick to get the right flexibility.
