This is a remix of Svw's cool Melting Dali Clock on Printables. It is a rendition of Salvador Dali's melting clock in his famous surrealist painting “The Persistence of Memory”.
I modified the clock hand attachment parts to be able to use readily available, inexpensive clock movements. This is the clock movement that I used. I also made the clock face and numbers one piece to use with an AMS, rather than gluing on tiny numbers. I found that the hands would catch on the numbers and stall the movement. If you don't have an AMS, you can paint the numbers on.
The tapered nylon(?) shafts of cheap Chinese clock movements are difficult to grab onto. To remedy this, take a small hack saw blade (fine tooth preferably) and lightly make cuts around the minute and hour shafts, near the base of each shaft, to make grooves for the teeth of the 3D printed hour and second tubes to grab onto. Be careful to only cut lightly--do not cut all the way through!
For the second hand, use a 1.0mm OD x 0.5mm ID brass tube 50mm long. Carefully crimp one end so that it will grab onto the second shaft on the movement. This is the brass tube I used. If you don't have a brass tube or this seems too difficult, you can omit the second hand entirely.
Assemble the hour disc and hand onto the hour tube. Do the same for the minute hand. Assemble the second disc, tube and hand onto the brass tube. Make sure the hands swing freely in each assembly. They should move 90 degrees with just gravity. Test fit the hour, minute and second hand assemblies onto the movement. Install a battery and make sure the movement works. Once function is verified, remove the hand assemblies.
Install the movement into the clock base using a nut and washer. Tighten the nut and install the clock face and frame onto the base. Carefully insert the hour hand assembly through the hole in the clock face and snap it onto the hour shaft. Install the minute and second hand assemblies similarly. Adjust the hour and minute hands to 12 o'clock and set to the proper time using the adjustment wheel on the movement and install an AA battery.
NOTE: I lengthened the second hand so that it would move more smoothly around the rim of the clock face. However it can still catch on rough edges and stall the movement. You may need to smooth the surface the second hand rides along to ensure smooth movement.
ANOTHER NOTE: If you don't want to use the second hand, I've provided a minute hand cap that will fill the hole where the second hand would go. The second hand is cool, but the clock will be a more reliable timekeeper without it.
Enjoy melted time keeping!
