A creative desk clock based on a 3d scan of a lemon.

Single and multi-color printing models are included as STL and 3MF! They work with all current and usual multi color setups.

Clock mechanism
This design requires a clock mechanism. They are widely available, cheap and almost identical in size. I used the bambulab clock components kit.
The case can be up to 56x56x20mm big.
The shaft of your kit can be up to 8mm thick.
The clock dial thickness is 5mm when assembled. The kits shaft thread needs to be at least 6mm long.
The hour handle needs to have a 5mm hole for my hand design to work
The minute handle needs to have a 3mm hole for my hand design to work
You can use the hands of your kit up to a length of 40mm to stay within the clock dial. Up to a length of 50 mm works but reaches beyond the dial. My design does not include a hand for seconds. If you want that please use your kit’s clock hands.

Instructions version M (multi-color)
Get a clock mechanism according to the info above
Print the Body, front, hour and minute hand in colors of your choice, preferably citrus themed
Put the front in by rotating it until it fits. It only works in one direction.
Insert the case from the bottom
Attach the hex nut onto the shaft
Push the hour hand onto the shaft – on 12 o’clock
Push the hour hand onto the shaft – on 12 o’clock - make sure that the two small “seeds” don’t block the movement of the other hand.
Rotate the small wheel on the back of the mechanism to the current time
Insert a suitable battery
To replace the battery a small stick like a skewer helps to get it loose more easily.

Instructions version S (single-color)
Get a clock mechanism according to the info above
Print the Body, 12 front segments, hour and minute hand in one color
Print the front and two seeds in another color
Glue the 12 segments into the front
Glue the seeds onto their respective hand – make sure to position them as in the pictures, so they do not overlap for better readability.
Put the front in by rotating it until it fits. It only works in one direction.
Insert the case from the bottom
Attach the hex nut onto the shaft
Push the hour hand onto the shaft – on 12 o’clock
Push the hour hand onto the shaft – on 12 o’clock - make sure that the two small “seeds” don’t block the movement of the other hand.
Rotate the small wheel on the back of the mechanism to the current time
Insert a suitable battery
To replace the battery a small stick like a skewer helps to get it loose more easily.
