For all those people out there who are not on a schedule, he we have the very thing for you, It's the “Who Cares” Clock.

This clock uses the cheap quartz movement, these are readily available online, the one I have used for this clock is the one with the 13mm Long shaft and the diameter of the shaft is 7.5mm , the hole in the clock face is 8mm but can be filed out to accommodate a larger shaft  movement.

The quartz version I purchased also includes a hanger which is fitted to the movement first before fitment, I couldn't use the plastic washer which comes with the movement as it was too thick, the movement nips up really well without it, I cut the pointers to suit the purpose as well.

No support or anything with this print, choose whatever colours you want, I used standard PLA.

Thanks for Looking.
