Pop-Up Target and controller

thingiverse

This is a compact test setup for pop-up targets used in "airsoft" practice sessions. Its primary purpose is to conceal and retract a paper target, allowing users to hone their acquisition skills and speed. This design can be adapted for various applications beyond its initial use. To build this fully functional system, you'll need several additional components: * An Arduino Nano or similar microcontroller board * A standard 9g servo motor * Two 608 bearings * A paperclip or a rigid piece of wire During assembly, I encountered some tolerance issues with the parts. The shaft was slightly loose in the bearings, but not by more than 0.004 inches at best. The bearings were also a snug fit into their respective holes and required some assistance from a Dremel tool to ensure they were properly seated. To prevent cracking, you may want to pre-drill the small holes that mount the servo. This device is compact, with a base size comparable to a credit card. Its primary intention was to test the underlying concept and create smaller units for airsoft practice sessions. The code for this project can be found in the thing files folder. Note: When printing multiple uprights, consider the risk of them breaking under stress, especially during airsoft practice. Alternatively, you can hang targets on the sides instead of the center to reduce the likelihood of damage.
