Citrus clock

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.
