5/20/2023 0 Comments Halloween 3d printing![]() 3D Printed Skeleton Hand STL for FREE download or a little pay All you need to do is to download the STL file, purchase the filament of your choice, set your printer to a layer height of 0.16mm and a temperature of 220 degrees Celsius and you are ready to go. it is printed in one piece, so it is easy to print even for beginners. This skeleton hand is a great decoration for Halloween or any spooky-themed event, and it is also a fun and interactive toy or conversation starter. The printing temperature is set at 220 degrees Celsius, which ensures that the filament melts and flows perfectly, creating a high-quality final product. The hand printed with an ultra-fine layer height of just 0.16mm, ensuring that every detail is captured with precision. The hand features articulated fingers and joints, allowing for movement, giving it a lifelike and creepy appearance. This skeleton hand is printed with a white filament, giving it a realistic and spooky appearance, as if it were a real skeleton hand. Let the paint dry and till then let’s see what else we need for this project.Introducing the 3D printed skeleton hand, a spine-chilling decoration that will make a haunting addition to your Halloween or any spooky themed decorations. In the end, once the parts are fully dry I might use some acrylic paint and add some shadow and details. In order to have the same color, I will use some spray paint and give it a few layers of paint. I passed two levels of sandpaper and they look better now. Finally, you should sandpaper all the parts, especially where we had supports, so we had a smoother finish. Anyway, now all parts are clean, more or less. So carefully remove everything from the inside and all the small holes. But the middle part has a lot of supports. For the jaw and the top part of the skull, that was easy. As you can see one was printed with two colors and that’s because while I was printing it, which by the way, it was around 30 hours of printing time, I was running out of grey filament so I had to pause the print and continue with gold color. Everything was printed with PLA material, 0.4mm nozzle and 0.2mm layer height and 20% infill and 2 perimeters. Inside the skull we have a lot of support for the 3D printing process. You have to print all of the parts using supports because none of them is flat and they all have round shapes. The jaw, the bottom part of the skull and the top part. ![]() So let’s start.įirst of all, we need the 3D printed skull so download my designs from below and 3D print it. To control the power of the heater and the pump we will need two MOSFETs which we can control with the Arduino. To push the smoke out I will sue a 12V fan. I’ve bought a few models and see which one is best. ![]() What we need for the mini smoke machine? Well I want to use the heating element of a vaping cigarette. We also want to make the skull react to movement so for that I will use a PIR sensor. And to protect and recharge the battery I will use a protection module with USB connector. To supply everything, I’m planning to use a 1S battery of 3.8V so we will need a voltage booster in order to get 5V for the digital part. It has enough power for an 8-ohm speaker so we also need that. This is very easy to control with the Arduino. To create sounds, as always, we can use a DF player with a micro-SD card and palace some mp3 files on it. For the LEDs I will use addressable RGB LEDs, the WS2812. To move the jaw, I will use a servo motor, a micro 9G. So let’s start with the components for the project.įirst of all, we need the 3D printed skull so download my designs from the next chapter below and 3D print it. That’s why, for this Halloween I’m making my own mini smoke machine so stay tuned till the end to see how to make it and how cheap are the parts that we need. You see, water mist is cool but sometimes you can barely see it. But the best part of this project is a homemade mini smoke machine. Inside I have enough space to add a battery, an Arduino a DF player and a speaker to be able to play some scary sounds. The eyes holes have spaces for some LEDs that we could also control with an Arduino for example. I’ve made this design so you could easily 3D print it, and then it would have a moving jaw that you could control with a servo motor. This time I want to make a scary 3D printed skull. Remember that last year we had a 3D printed pumpkin that was able to play sounds and was creating water mist out of its mouth together with some addressable LEDs. ![]() We are around Halloween days and I want to make another cool project.
