mine printed perfectly the first time, tried it second time the one with the hook the gear is really loose. Both printed with PLA. Will try again.

Thank you for the tip! I used Simplify3D to slice it. I will give your scaling suggestion a try.

Different slicing apps prepare files for printing differently and different machines print differently, albeit slightly, but that can easily be enough to cause the issues you have described. With My Makerbot's / Makerbot Desktop slicing app I've never had a problem... however if yours is loose reduce with gears falling out reduce the scale uniformly by 3-5%. That should reduce the clearances adequately so it won't come apart...,.

I printed this with PLA on a FFCP and found it a little too loose. The gears pop out quite easily, especially if dropped on a concrete floor!
