I wanted a workshop clock that was different to the table saw blade clocks that are sold by Craftsman, yet remained easy to build and cost less than $60. I settled on a Giant 6X life size Caliper. This is not a exact replica instead it’s a simple to build clock that looks a little like the standard engineers caliper.
The overall length of this caliper is 60 inches but you can build it to whatever length you like. I suggest you print the clock housing first so that if you want to make it smaller you can then measure the cutout and reduce your main shaft down to fit.
This was printed on an Anycubic Chiron which has a 400mm x 400mm bed so again you may have to reduce the size of the main housing in Cura or cut it in half in Meshmixer to fit on a smaller bed size. If you do reduce the size you will need to find a smaller clock module

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
