this quick print in place uses cylindrical bearing mechanism to ride smooth, it uses a tolerance of 0.15 and will not fall apart. To lossen the cylinders I recommend you stick a pin or or a needle in between the cylinders and spin it using the pin.it is extremely fun to play with and would make for a great gift. I have also made a version with 0.20 tolerance but I have personally not tested it so I don't recommend printing it unless the 0.15mm is giving issues, i fear the cylinders might slip out.
