Reusing Cardboard Spools: Disk Launcher

For my last entry of the reusing cardboard spools contest, I designed a simple disk launcher where cardboard spools can be used as ammo. Unfortunately, due to time constraints and a failed print, I am unable to show the finalized printed model and test its functionality. The last picture shows an earlier printed model, but the one in the download is different due to a mistake I made in the deisgn, making it inflexible… Feel free to give me any feedback so that I can improve on this project.
