Atom Clock 25cm HDNC03

Dimensions Assembled: 250 x 250 x 35 mm (9.84 x 9.8 x 1.4 inches)

One in a series of bold wall clocks inspired by mid-century modern aesthetics, and the iconic clocks designed by the office of George Nelson for the Howard Miller Clock Company in the 50’s and ’60’s, many of which are currently manufactured by Vitra.

• The clock body is a two-part assembly with a dial firmly snap-fit on a clock movement cover, without the need for glue or any additional hardware
• The compact clock movement cover includes a small hanging hook
• It requires a standard clock movement with a threaded shaft: 10mm (3/8”) diameter, 6mm 1/4” min. length
• Clock movements sold online or in hobby stores usually come with a set of hands of your choice. The length of the minute hand should be approximately 65mm from the center of the hole/shaft
• The STL files include one set of press-on hands as shown in the pics. Follow the instructions below and in the pics to customize the holes for your movement

Objects in the photographs were printed on a standard desktop 3D printer, without secondary operations.

Specifications and Recommended 3D Printing Settings

Required build volume: 250 x 250 x 22 mm

Nozzle: 0.4 Layer: 0.2 Supports: YES Infill: 15% Gyroid Scalable: NO Tested with: PLA

Press-on hands: The individual models for the hour and minute hands include a pilot hole, you can carefully drill the pilot hole to the required diameter. The models also include additional reference geometry that will automatically align the pilot hole at the center of the build plate (or right-click > center). Follow the instructions in the pic to use a cylindrical negative part to create the hole you need.

The tolerance of the hole will vary depending on the material used, printing settings, and other conditions. Typically, a hole 0.3mm to 0.4mm larger than the shaft diameter will work for PLA. You will probably need to print the hands more than once to get an optimal fit.
