Paper Airplane Launcher
FleetingI love the attach in https://www.printables.com/model/1304976-paper-plane-launcher

trying the slingshot from the helicopter seeds launcher https://www.thingiverse.com/thing:7337818/files

It is meant to send helicopter seed, like
the rubber band does not stick to the slingshot and the seed does not fly very well.
