Dulton-Style Double-Face Wall Clock with Swappable Magnetic Faces

Inspired by the classic industrial Dulton double-sided wall clock, this design recreates the iconic look in a low-cost, fully 3D-printable format.
It features magnetically attached, swappable faces, making maintenance and customization quick and simple.

All required hardware is easy to source, and all printed parts are available on the Bambu Store, making this a straightforward build for most users.

Unlike similar designs, this version features a seamless single-piece main body, giving a cleaner appearance and improved strength. The body prints in one piece and requires some supports.

Assembly Instructions

1. Insert 4× magnets (4 mm × 2 mm) into the clock faces.
2. Insert 8× magnets (4mm x 2mm) into the main body.
3. Install the clock mechanisms into both faces.
4. Attach the wall mount to the wall using suitable fixings.
5. Slide the main body down onto the wall mount.
6. Snap the two clock faces into position using the magnets.

Battery Replacement

To change the battery:

• Pinch the clock mechanism from the centre.
• Pull the face straight off.
• Replace the battery and snap the face back into place.

No tools required.

Update 

I've added a version for Non-AMS users. Add a pause to the slider at 3.2mm high and change the filament colour to print the text / graphics. 

Future development

• Make more faces - let me know in the comments if you have any ideas and designs you want
• Make an A1 Mini version - currently this only fits on an A1 / P / H size printer.
