Its the perfect small sized clicker- 

Designed with glorious keycaps ( low cost keys) 

Button Fits snug over key - print and go. 

Prints with less than 20g of material. 

No support needed - Brim of 5mm Recommended.

Recommended: add a dab of glue to the bottom where the key goes - ensures it won't come out. 

Tolerance is very tight - button goes on the key very snugly- may want to add glue to button PLA with looses after some hardcore play.
