CAD Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below:

  • twt-handle.stl
  • twt-horn.stl
  • twt-front-plate.stl
  • twt-frame.stl
  • twt-front-ring.stl
  • twt-base.stl
  • qtpy-holder.stl

CAD Assembly

The servo is secured to the front plate with screws. The bezel snap fits over the frame. The front plate snap fits onto the frame. The base plate is secured to the frame with screws and hex nuts. The QT Py snap fits into the holder. The holder is secured to the base plate with screws and hex nuts. The handle is secured to the 3D printed horn with a single screw. The handle assembly is secured to a stock servo horn with screws. The stock servo horn is secured to the shaft of the motor with a single screw. 

Build Volume

The parts require a 3D printer with a minimum build volume.

  • 110mm (X) x 110mm (Y) x 100mm (Z)

Label & Graphics

Download the vector template and modify the graphics to your desired set of emoji's.

Use an inkjet color printer with sticker project paper to easily adhere the graphics to the 3D printed face plate. 

Label Dimensions: 92mm x 46mm

Ensure the graphics are not scaled when printing. Reference the dimensions above for correct size and scaling.

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, STL and more. Electronic components like Adafruit's boards, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.
