A simple Bullet Clicker fidget clicker, containing one external clicking key found here

There are 4 different profiles with 2 different models.

2 profles for a hollow point tip

2 profiles for a smooth point tip

Bambu Gold

Bambu Gray

You will need to place one key in the center of the top for the clicking to work. IT IS AN EXTERNAL PIECE THAT NEEDS TO BE INSERTED. 

All my prints use Bambu PLA Basic filaments and I also use a Bambu Cool Plate (SuperTack) 

I do not know how other filaments will print and how it will print on other plates.
