T-800 Terminator Exoskull in four pieces

thingiverse

Just in time for Halloween! I like this "Thingi" (Thank you DEL_1979), but after one failed print attempt, I thought it was too difficult for my inexpensive printer. So, I cut the front half of the skull into two pieces and removed some of the floating unattached parts of the model to simplify printing. This approach eliminates the need for supports inside the large cavity. Still, I recommend using supports for other features. To ensure a secure fit, I added locating studs to each piece, which snap together easily. Next, I applied the same technique to the back half of the skull. The same process was used, with locating studs added for a seamless connection. I also suggest using the remixed jaw, which I didn't print but identified some potential issues after printing the original. You may prefer the stand from the original or use a remix instead. Due to my printer's size limitations, I printed this model at 90% of its full size. I plan to add electronics, including a Circuit Playground Express and Servo Motor, inside the skull. I'll update this post once completed. Update October 29th, 2018: My Halloween project is now complete! Using the front half of the skull, I installed two LED eyes, a servo motor for the jaw, a Circuit Playground Express, and a battery. The entire setup is sound-activated. I've included a video to show off my creation. To add some extra flair, I used magnets to create a holder that screws onto the front half of the skull. However, since I printed the skull at 90% scale, I've made available a second file with the correct magnet size holes. The magnets measure 6 mm in height and 12.5 mm in diameter.
