Tell us about yourself!
Thanks loads for updating the files so quickly! The build is quite a good one and I managed to locate the Lunar Eclipse set to give it that Zing, plus printing the gears in Gold filament adds that touch of class(Not that it's lacking!) Let me know when you finish the new drive system, as you are correct with the slippage problem I had similar with the Solar System Orrery I'm still fetteling. As a suggestion, try Epoxy on the shaft? it's strong grip may help?
