Locking Pins For Vend Collar
thingiverse
This is just a little bolt you can use to 'lock' everything together. It just loosely friction fits within itself. *This particular .stl is untested.* The one I used was slightly longer and I clipped a couple mm off so that it could be inserted, so I removed a couple mm from the bolts and this should fit now. If anyone has any issues, you can do the same but please let me know so I can update the file.
