Hopper Repeating Crossbow
thingiverse
I wanted more ammo capacity for this repeating crossbow so I added a hopper. It holds about 30 bolts. I recommend adding a paper lid on top so the bolts won't fall out and adding a little tape above the trigger to reduce jamming if your printer isn't detailed enough to print the notch. In the photo, you'll notice I added a rubber on top to auto-cock the crossbow.
