Geocaching fake lock for bisontubes or small tubes

A fake lock that will fit a bison tube or another small test tube.  The test tubes I am using are flat-bottomed 1ml ones from amazon. I also made an additional profile for bison tubes. If you find a capsule model on makerworld, and you send me the dimensions, I can modify the lock to fit it.  The lock is printed in two parts, the main body and the curved bar thing, which are held together with friction. Because of this, some printers might need slightly different tolerances.
