Treasure Hunt Bolt

This was an idea I had for hiding messages for city-wide treasure hunts. It is simple but effective. The bolts can hold a simple rolled up message and can be installed in square traffic posts, preferably near the grass where they won't be immediately obvious. These are made with some small nubs to be finger tightened into posts for treasure hunts, not permanently installed with tools. A couple of notes on use: Don't stuff the note all the way into the sleeve, it will be really hard to get out. Leave room for fingers to grab out the note. Don't close too tightly. The print orientation required for the screw threads creates layer line weakness along the length of either shaft. If you screw them together too far or too tightly, you will cause a split. This is especially the case for PETG, which I still recommend because it will weather the outdoors better than PLA. Feel free to use some fun colors (I only had white PETG HF at the time) and please post pics and feedback! I love hearing how
