When printing teunKeusters nice clock I stepped into problems with wobbly backplate and gears. So something had to be done to save the day.

Backplate
backplate_double.stl was derived from the original plate. The designe was cut so all the gear stubs have the same height. The two elongated pins for main and big gear go thought both plates and stabilise it. The motor screws (~M3x30) also mount throught both plates.

Bearings
I found matching axial bearings that require only minimal changes in the original design:
