Radiant Chime (Christmas ornament)

Hark! how the prints
Sweet 3D prints
All seem to say
“Bells print away”
Christmas is here!
Very, very, very, very radiant
Very, very, very, very radiant

The bell is covered in a glitchy geometric pattern with a Christmas-y feel, resulting from a noise function. It is designed for vase mode printing, ensuring a perfect surface finish. In order to print this clearly-defined pattern in vase mode, we must use a low layer height and a wider than usual line (but easily printable with a 0.4 mm nozzle). Combined with a low printing speed, these settings will really bring out the details.

All components print without supports in their default orientations. There is a little bridging in the rope and ribbon units, which is easily handled by your printer. No infill is required for the rope, holly, and ribbon units.

The parts are designed to hold together without glue. To assemble the ornament:

1. Screw the connector on the ribbon unit
2. Place the holly leaves in the corresponding socket of the rope unit
3. Screw the above assemblies together
4. Screw the assembled top and the bell together

A bell printed in a white filament, will make a great festive diffuser for your LED tealights.
