3D Printed Toy Accessories

Challenge: Student wanted to create a series of 3D Printed accessories to use as part of a play set involving horses and show jumping.
Background: This student has themed various designs during the year based around a 'horse' theme, as it is something that she is passionatae about.   She was looking to create specific accessories for some of her existing toys, hence she was trying to produce something of a very specific size to scale.   She was able to source some online freely available materials and designs and then set about adjusting the size of them so that she was able to have them produced for the correct size (which she was able to do on the second attempt).   As the time was relatively short we had contemplated a series of prints in different PLA that would feature the same design and then be combined for a layering effect with differing colours.  The student in charge of this project (and to also answer a question that has come up recently, the student is also responsible for the conversion of the design into the 3D Printing Computer software and the full printing processs - the limit of the teachers input at this stage is to check the production time for the print, sometimes once it is already in progress to simply ensure it is a reasonable print from the student.  The student in this case is a Y5 student who is usnig the 3D Printer for the first time significantly. 
Level of Difficulty - Low: this print require a redesign for size, otherwise the design aspect was minimal as it was a Tinkercad freely available file.
Timeframe: One hour forty minutes.   This could be modified for the individual poles etc which were ten minutes each. 
Size: The size of each of the items that were part of the set varied significantly.  The poles that were featured for the dressage jump was 3mm thick and 60mm long.
What we would do differently: Minimal - the student considered the project to be extremely successful, and other than the relative failure of the first print, given that it was not to the students satisfaction relative to the size of the original toy. 
Next steps for the student: To move onto other projects, perhaps to use their talents and skills to create original pieces of accessories instead of relying on open sourced projects.
