I completely reprinted most of my clock parts because it was not working. Now I can't get the dial to fit onto the frame. Are the arbors too long or something like that? I followed the directions exactly and they're the right size. I tried to drill out the holes in the dial and back frame to allow for more clearance. This just seems to have made my problems worse. Now all the gears wiggle around and do not stay put. Maybe if I can get the frame to fit correctly I will solve this problem and the frame will keep them in place. I need a bit or help though on why the frame won't fit.

One of the assembly steps is to drill out every hole in the frame that will receive an arbor. This is required because holes often close up when printing. Different printers will end up with different size holes. The design cannot compensate to fit every printer without making the holes way too large for some printers.
The simple solution is to drill the holes to fit. A handheld pin vise works best so you can slowly drill each hole and feel when it reaches the bottom.
If some of the gears are able to wiggle around, then it seems like you may have drilled through the bottom of some of the holes. The arbor will be able to move so far in one direction that the other end falls out. You may be able to rescue the design by using longer arbors. Each one will need to be cut to fit. There should be about 0.5-1mm of end shake when they are at the proper length.
