The author remixed this model.
I modified the clock hand attachment parts to work with cheap, readily available clock movements. The plastic shafts are lightly saw cut to add a groove for the hand parts to grip onto. The clock face and numbers have been combined into one file to allow the use of a mult-material system (e.g., an AMS). There are numerous other minor modifications to make it easier to assemble.
