“A kit to build a mechanical display that cycles through the numbers 0-9 by turning a crank.
Do you love building mechanical contraptions? Complicated looking gear trains that perform some task?
Then this kit is for you !
However, beware. It is not for the faint-hearted. The assembly instructions are 26 pages long. The counter comprises of well over 100 parts.
If you want to take it even further you can install a motor and drive it automatically.
NB: The counter only counts in one direction, up. It cannot be wound backwards. If you’d like it to count down instead, grab the reverse gear set https://cults3d.com/en/3d-model/gadget/reverse-gear-set-for-7-segments
3D PRINTING SETTINGS
I printed my units with a 0.2mm layer height on an Ender 3 with the standard 0.4mm nozzle in normal PLA. My printers are tuned for accuracy, well leveled to avoid elephant foot type artifacts and minimum stringing.”
