Black Widow Infinity War Eskrima Stick

myminifactory

Important Update 2018-04-28 The original design is robust enough as a display prop, but it feels somewhat unsteady as a cosplay prop. After using these props for a day (nothing broke and I did twirl the staff and sticks around, but didn't hit anything with them), I decided to give another look at solidifying the design. I came up with three quick-to-print parts that replace the connector ring parts and really help make the build solid without any glue. I printed mine in clear PETG because the new design fully wraps the LEDs inside. The new look is a bit more diffused, but actually appears brighter from a distance. I have added a comparison photo where the new version is on top. PETG is soft and slippery, so I didn't tap the holes at all and just bolted the screws on. The old design relied a lot on the screws being tight for rigidity. The new one just uses them to keep the parts together and the rigidity comes from contact between the parts. Tolerances are fairly tight, so depending on your printer, you may need to sand the insides of the male segments a tiny bit to get everything to fit. If your build has 9 joints, you'll need 7 of the TubeConnector parts and one tip and hilt part (double that for two sticks or a staff). Original Post: This is my interpretation of a weapon recently seen used by Black Widow in trailers & photo shoots for the Infinity War movie. The full build includes WS2812B NeoPixel strips, Arduino Pro Mini. Disclaimer: this is a cosplay/display prop and it is not designed for actual combat. Some YouTube videos showing my first prototype: https://www.youtube.com/watch?v=tbSOtF_mO4Y https://www.youtube.com/watch?v=YY8wmjXqZDc The software was mostly ported from my Kryptonite Sword project, but I will be making a custom version soon. Ask for help in the comments, if you start working on the electronics and need wiring instructions & software. Here's the source code repository: https://github.com/jmunkki/eskrimastick Alternatively, a USB power bank can be fitted inside the hilt and a TV backlight LED strip can be used for lighting. This will give you a nicely lit up weapon, but no animations & active features. This item is highly modular, so you can upgrade to a full electronics build later on, even if you start out with no LEDs at all. In addition to the 3D printer parts, a number of small screws will be needed. The design was created for M5 x 5mm socket head (Allen) screws, but M5 x 6mm screws can be used as long as you are very careful not to damage the parts. A short segment of 1.75mm filament can be placed in the tip lens part to activate the microswitch, but a bit of plastic tube from a Q-tip will also work great. Here's a referral link to Hobbyking. If you sign up, I get points, which can be used for store credit, so not actual money, but I'll be able to use the credits for filaments and other hardware. I bought the M5x5 screws and the Hobbyking Silver PLA filament from there and can recommend both (while you are at it, pick up some of their flexible filaments, at least the black): https://hobbyking.com/en_us/customer/account/create/referral/3MDCXNTAWMCAXNT/
