The clockface is printed together as a multi-colour print, both light numbers on dark background or the reverse work quite well. It has a standard 56mm square mounting for a battery clock mechanism and the hands are designed to cover a 8mm mounting shaft with a 5.7mm hour shaft (smaller minute and second shafts are not used).
I printed in both PLA and ABS with good results, but I think the PLA is best when used with a 0.2mm nozzle (see the silver and black version). There is no need for supports on the clockface, but printing the hands with supports gets a better internal finish for connecting to the mechanism.
All work was done in Tinkercad. The clock face has the numbers cut out using a copy of the numbers part as a hole, then the pair are aligned for printing. Have changed the number font and size a few times as the project progressed.
My clocks are printed on an X1C using Babmu Labs filament. The best quality is at normal speed using a 0.2mm nozzle, but successful prints were achieved using a 0.6mm nozzle and Sport setting as well to get the thing printed in a couple of hours.
