Knockdown target

A Knockdown target intended to be used with my pokeballs https://www.printables.com/model/617378-pokeball or similar size & weight ball. This is designed in such a way as to only fall down if the plate is hit rather than the lever arm. This was a fun project to demonstrate a mechanism for me. It works best when place on a flat and level surface. 
The base is just small enough to print on a Ender 3 bed. 

Reset the target by lifting the arm and pushing the target forward to engage the lock on the base. 

When assembling, the pin should press-fit in without the need for glue. 

Most parts can be printed without support. The main lever arm and the top slider will need a bit of support for the dovetail. The Target face with dovetail attachment will need a lot of support if printed face up. I printed face up only because I intend to add a logo to the face. Otherwise, it should print fine face down. 

Strength 1.2mm walls and 10% infill should be fine. The lighter the top is printed, the better it works. 

Print the pins one at a time, or using the “sequence” option in Cura to fit them all on the bed at once. (I did have to manually modify the gantry height in the machine settings to do this).
