Description

Show original

A winter cocoa mug, filled with rotating cocoa, marshmallows, and a bathing gingerbread man. A small TT Motor DC5V is located in the mug, which creates a slower rotational movement via two gears, gently rotating the cocoa. An additional gear reduction ensures that the spoon appears almost straight, creating the impression that someone is constantly stirring

The model is entirely 3D printable – except for the motor and five screws. The rest is assembled by fitting or gluing. The GIF on the start page shows the rotational movement

Materials

3× M2.5 × 8 mm
2× M2.5 × 12 mm
TT Motor DC5V 59RPM CCW Single Axis
Superglue for the spoon handle, and optionally for marshmallows and gingerbread man

Notes before assembly (read before watching the video)

Marshmallows are numbered, align the matching number on the cocoa and glue it
Gingerbread man consists of delicate individual parts
- the lower button protrudes slightly, later disappearing into the recess in the cocoa
Glue the spoon handle to the small cocoa disc (mind the recess)
Between the rotating cocoa top (upper cocoa disc) and the lower mechanism, there is a flat, square connecting insert. This connecting part must be inserted so that the side that was on the print bed faces downwards towards the mechanism
For the motor, make sure that the two front mounting holes are present (as shown at the beginning of the video). These holes are not clearly specified on the official product page – they are required for the M2.5 screws
It's best not to glue the upper cocoa disc, it facilitates later access
