Hollow Shadow Clock - Projecting Time!

Please do ‘like’ this project here on Printables. It really does help me to continue to design, document, and share these projects for free. 😊

3D Print and assemble your own Hollow Shadow Clock with amazing projections and magical motions! 

 The Hollow Shadow Clock is a time telling marvel. First of, can you figure out how the hour hand is being controlled? Once you’ve solved that, continue to marvel at its larger then life ability to project an analogue clock face onto any surface. Control the colour and brightness with two discreet buttons, or connect to your clock via its integrated web-server and WiFi connection to program an automated weekly schedule. Have it wake you up in the morning, or light up to remind you it’s time to finish work! 

This is a predominately 3D printed project and my detailed instructions will ensure you have every success in building one of your own. 

This project is based on the Hollow Clock project by Shiura: https://shiura.com/

Update April 2025: I've added a 5mm longer hour hand for anyone who finds the magnets can't hold theirs in place.

I've been using the OmniFixo 'helping hands' for this project and have found they are significantly better than alligator clips and traditional methods. I've not been paid to say this - but they are something I genuinely personally recommend. Find out more here: https://omnifixo.com/en-gb

I use a Prusa MK4S for my projects and highly recommend both it and the Prusa Mini. If I inspired you to take up 3D printing please consider purchasing a printer via this link: http://shop.prusa3d.com/#a_aid=diymachines
