3D Printed Watch Stand

Design as shown from above
Challenge: To produce a working watch stand suitble for the storage of a worn watch.
Background: This design idea actually came from a parent of the student concerned who challenged the student to create a watch stand so that he would have a better organised room and his personal posssesions would be in a better place.  The student has been responsible for a number of designs on this page and was working a an advanced level (for a Y5 student in New Zealand, which makes the student ten years old).  The student came up with the idea, the design - including using Tinkercad to provide the key elements and shapes as clearly shown.   The student came with the entire project in mind and the teachers only input was to provide the hardware to complete the
Side of design
Level of Difficulty: Low - the design shown above has the three key elements.   The student designed the base, sides and main bar in under three mintues.   The dimensions took slightly longer however the student wanted to print the design first, to see how it looked before adding any additional features (see below).  This sort of design should be easily completed by students of any age.
Timeframe: The design took ten hours on a regular infil setting and as with every recent (2017) design on this blog was completed with a 8mm nozzle.  As an aside I personally visited a school last week who had an Ultimaker 3 and had completed a first set of prints, I would hesitate to suggest based on the speeds etc that they were using a 4mm nozzle and high infill settings - this was going to prove to be extremely problematic moving forward for a class/school situation.
Size: The base plate for the design was 14cm across and 7cm wide.   It was a height of 9cm.  It was discussed during this print that a similar designed Headphone stand would be worth investigating for a future work project/design.  The width of the plate was 5mm.
What we would do differently: This student was intent on running a print prior to discussing the adding of personal touches to the print - the obvious basic one was a name on the plate or the side of the design, which would have had minimal design required.   The most pleasing aspect of the design was that ever aspect of the design came from a ten year old who had identified the problem, a soultion, came up with a practical design that worked and the featured print was the first attempt.
Next Steps for the Students: Personalising the design is the obvious one that has already been discussed.  We are investigating the practicality of creating some form of headphone stand or wall mount, although the size may vary.   Also discussed student adding a draw, into the base of the design which has him thinking of ways to complete it successfully.
