3D Printed Minature Stationary Stands

Challenge: Student wanted to produce a scaled down version of a typical stationary holder.
Background: The student concerned had an idea of what she wanted to produce and had examples in the classroom that showed what could be produced.   The student was able to produce a basic design model and then personalised it with her name, and wanting to further add an additional touch of putting the animals paws in the bottom right hand corner of the design.   All in all as an introductory attempt at 3D Printing the student managed to complete all of the anticipated goals - working by herself etc. and was able to produce something that worked perfectly.   It should also be noted that this print was produced with zero 'rafting' or waste PLA so that the student was able to spend no time removing any of it, and the font for the name on the plate worked perfectly.    The only issue with the design of this project was the size - the student had intended it to be a smaller version of the full sized type of project that students had created and are detailed on this blog.   The student who created the project

was concerned that by reducing the size that the project would not work or that the storage would be compromised by the reduced size - this was not the case and while the scale was reduced the purpose worked extremely well.  It was also suggested by the student that this could be used for storage of jewellery or other items.
Degree of Difficulty: Low/Medium - this was the students first design and was able to use Tinkercad to create and manipulate the shapes that were required.   She was able to create the balance of the design easily, but she has a talent for design.
Size: As shown in the photograph to the left the design was 110mm across and the base of the unti was 100mm high.   The lettering for the name and the paw print was raised 5mm.   The towers that are the storage part of the design, the left and right towers are 70mm high with the middle tower being 50mm high. 
Timeframe: Seven and a half hours.    The design of the unit and the measurements were required and would be the minimum to make the design workable.    The printer was using the default settings for Tinkercad, which is essentially 20% infill and the Ultimaker 2+ used a 8mm nozzle.
What we would do differently/Next Steps for Students: Nil - the student was thrilled with the results and it was considered extremely successful.
