Instructions:

1. Choose a model to use with your kit:
   • Browse the 3D models above
   • Use associated link to download the ZIP file
   • ZIP files contain STL ready to print and STP files for easy customization
2. Print your chosen model:
   • Print the STL models or customize the included STP files (recommend Fusion 360)
3. Assemble your Electronics Kit:
   • Solder components to the PCB (see image below for placement)
     • Note:  Coil has two wires, one must use the pair of holes on each side of the PCB (see graphic on PCB)
     • LED polarity is important and must be installed with flat side (negative) per the image on PCB
     • Transistor polarity must be correct with flat side oriented as shown.
     • 
4. Finally, assemble the electronics and printed case.  Try different cases or design your own!
   • Note:  Not all 3D model designs use all parts.  Hardware such as the wood screw and magnets may be used in alternative designs and some that have not been released.
   • If you design your own, be sure to share it with the community in our Thingiverse group!
