Really cool build. It looks a little slow from what I can tell from a 12 second video. You want to count full rotations and figure out how many revolutions per minute. around 40 is ideal for that size barrel and I am guessing yours is closer to 24. It is not a matter of running longer it is more about the proper action in the barrel. It takes a certain speed to get the proper rise and fall of the rocks.
The other advice I would give is to slide some rubber tubing over the threaded shafts. Tumblers run 24-7 for months at a time and that threaded shaft will really tear up an expensive rubber barrel over time.

First, welcome to the forum. Second, that's a class build for sure. I agree with Chuck on putting some rubber tubing on the roller rods, which would increase rolling speed some. I stopwatched your vid. twice and averaged ~20 R.P.M. for the barrel, 40-50 more ideal.

3D printed? What a great idea... this is a real DIY tumbler. To adjust the rotation speed you should be able to re-print the couple of gears (red and black) varying their diameters to obtain the correct ratio...best wishes
