Disk Launcher
thingiverse
Disk Launcher inspired from a Kiwico crate that my son received. If printing at smaller size, reduce the disks and trigger slightly more than the launcher (e.g 73% for trigger and disks, 75% for launcher) to leave a sufficient play. You may want to do that even at full scale depending on your printer's precision. See it in action at: https://www.youtube.com/watch?v=5T8XNOCicJ0
