Printed with Marble PLA for the frames and a translucent PETG for allgears and small parts. I have been having great luck with the PETG in all my clocks, better than using PLA gears. A dry lube certainly helps the PLA but other than have to remove a bit of stringing, the PETG works great. I have been able to get these to run within a minute per day which is plenty good for me. Thanks Steve for all the cool designs, Al
