About this model

The popular Hollow Clock 4 is now thoroughly improved and refined. * The ring is much thinner and neat (only 7mm) with indexes. * There are no screw heads on the exterior (except the center of the hands). * USB-C power inlet is placed on the back of the base. * Ratchet mechanism makes the clock reliable against the slippage (out of step) of the weak stepper motor. * Accuracy of the clock is much improved by the crystal oscillator of RP2040 based microcontroller. * Easy time adjustment method (pull out the display ring, adjust, then insert to the base) is carried over from the previous model, but the ring is now securely fixed. * Totally redesigned to exploit the texture of build plate and layer lines.
