A Sweet Trick or Treat Bowl Made with a Severed Hand Imagine receiving this sweet treat filled trick-or-treat bowl. The bowl is designed to look like a coffin, which already sets the tone for the frightening and spooky ambiance that Halloween provides. Inside this terrifying design is an incredibly cool severed hand made from Filaflex material, allowing it to flex just like your average hand would, but in a really disturbing manner. When you pull on these "tendons" at the back of the coffin-shaped bowl, you can watch as it appears to animate and grab onto anything it sees. Filaflex material was chosen for its very realistic flesh color, making this severed hand even more realistic looking when used inside the Makerbot translucent purple coffin and surrounded by a pool of fake blood from Makerbot's Translucent Red material. In order to really make use of the design that is presented in these steps below, please make sure to take some time to watch our demonstration videos of the Sweet Trick or Treat Bowl in action. You can find them on Gyrobot.co.uk and also on Facebook.com/GyrobotUK for those that are fans. Here are all the necessary instructions in order to get you set up and running to print your very own severed hand: Printing Steps Step 1: Start by printing the "Blood Skirt.stl" which is a vital part of your bowl. The skirt comes out much more real when printed using red filament. After that, make sure to print out the coffin with the specifications outlined below in steps. Then move onto and start printing all five "Ring Pulls.stl." These pieces need to be printed without any supports because of their very simple nature. Lastly, ensure that your last printouts include both "Finger Hinge Plate.stl" along with its associated parts. Please use flexible filament when doing so. Assembly Steps To put everything together follow these next few steps. The Fingers and Ring Pulls: When it comes time to put all the pieces together, there's a small diagram called "Base Hinge Orientation.png" which illustrates exactly how the fingers at the base are placed so that they aid with finger return. Make sure you have the hinge at 45 degree angles as you push them into their holes because that's what allows your finger to properly swing back when let go. In particular, the hinges on the thumb tendons need a little more work since the process for assembly of the bases are quite similar. Assembly of Tendons Pre-cutting and threading: Once all is said and done start threading each of these pieces together by pulling the pre cut lines that we made earlier into their associated ends to secure in place. We recommend you thread from both holes of the tip of fingers until one goes through them both. To finalize any excess line simply take it out. Finally make a "none slip knot" with whatever's left over so your strings will be secure, before snipping it and removing anything unwanted strands left behind using your finger for leverage and forceful cutting motions. After tying that in place with super glue seal it up to ensure there is absolutely no movement happening between parts while holding on tight. Step 5: To complete all steps put it into its holder made of Filaflex by inserting screws into them, followed threading of tendon through corresponding holes before securing hand to coffin via tightening down. Last thing do - tighten that blood skirt which needs some kind help because they need super glue applied then tie off remaining ends left on ring pull for finishing touches.
