A simple panic button themed fidget clicker. You can change the colors to whatever you want too! 

The notch CAN be attached to the top and printed as one piece, but I choose to print the notch separately and glue it in. The choice is up to you! I use E6000 glue. Super glue will work just fine too.

If you don't mind layer lines, print the top flat. You can use adaptive layers to help, but it will not completely eliminate the layer lines on the curved surface. You can always print it sideways, but it will increase the print time and the need for supports. 

The bottom portion has a loop for keychain hardware, and the hole is designed by Muwiart to house BLUE keyboard switches. The entire keyboard switch should fit into the bottom hole, with only the top blue part sticking out.

Happy printing! I have an alternative top that's a little less family friendly that I will be uploading as well.
