Madame Leota Headstone Eye Animatronics by legochuck

Last crawled date: 3 years, 4 months ago

These files were used as part of a larger project to create a working animatronic Madame Leota Headstone from Disney's Haunted Mansion attraction. The rest of the headstone was created using pink insulation foam and vacuformed plastic. The eyes are approximately 52mm apart. Similar to the actual headstone in the theme parks, these eyes only move side to side.
In addition to the printed parts, the following hardware was used:
2 10mm M3 screws
1 18mm M3 screw
3 M3 Lock Nuts
4 M3 Washers
26mm Half Eye Green: https://smile.amazon.com/gp/product/B00EQ28XRK/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
2 SG90 Servos: https://smile.amazon.com/gp/product/B081ZY23V4/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
Arduino Nano
5V Power Supply
One of each part should be printed with the exception of the eye stalk, which should be printed twice. To assemble, attach the eyelids to the front of the chassis using the longer M3 screw, placing washers in between each eyelid and the chassis. The head of the screw should fit in the right eyelid while the lock nut will fit in the left. Next, attach the eye stalks to the chassis with the shorter M3 screws, with the screw head fitting into the slot on the eye stalk and the lock nut protruding out from the bottom. A washer can be fitted in between the eye stalk and the chassis. Two servos can be added to the chassis slots, the horizontal one controlling the side to side motion of the eyes, while the vertical one controls the eye lid motion. The screws included with the servos should be able to drive into the mounting holes in the chassis. Paper clips can be bent and fed through the actuation holes to connect to the servos. Once everything is in place, the plastic half eyes can be glued onto the eye stalks.
The arduino sketch used for controlling the eyes was also included. Both the servo positions for the gazes and the arduino pins the servos are attached to will most likely need to be changed to fit your specific installation.
Parts were printed on the Prusa i3 mk3s in PETG at .2mm layer height. With correct orientation no supports should be necessary.
