CD Clock on Thingiverse

 

Today I put a clock design up on thingiverse, here is the link, https://www.thingiverse.com/thing:7316196 . 

 This is an old design for me and up till now I have resisted making it public. It needs a cd, a rubber band and a clock mechanism to work. Its standard position is hanging on a wall, but it also has 3 holes for 3mm legs to make it a desk or table clock - just add skewers!

 The 2 centre parts of the design are dependent on the clock mechanism you are using, but the numbers should all attach radially to any DVD or CD using a rubber band as a fastener. The design is a version of a previous design, the printer spool clock, also on thingiverse at https://www.thingiverse.com/thing:2531561 . As well as a clock, this design could be used as a counting toy, and a way of learning about factors. Have fun! 

As well as plain clocks, I have experimented with variations, most notably face rotation clocks (the hour hand is anchored and the whole face rotates) and tetrahedral - cd - clocks. Some related posts are
