3D Printed Stationary Holder: Developing the next level of prints

Challenge: To take a standard 3D Printed stationary stand and combine PLA (prints) and add additional features and designs to increase the appeal of the overall print.
Background: Students are well versed in producing considerably large prints to serve as stationary holders or desk tidy items for the students.   The design of these come as premade or students are able to use Tinkercad to quickly take some of basic shapes and group them, creating a stand using the basic shapes (as shown in the photograph on the left).    The student responsible for this design is a nine year old Y5 student who has self taught himself to identify projects that he could complete with his developing skillset.   He is using Tinkercad in the classroom where appropriate but also in his own time at home to come up with designs such as this which he is subsequently bringing into the

classroom - the teacher role at this point is to check the prints, discuss the intention or purpose of the prints and press the print button.  It is not to create the project or direct the students. 

The challenge for the student is not to create in this instance - it is to challenge the student capable of producing a product like this and look towards combing PLA, spray painting the PLA and adding the addition of 'wow' factors.   The student is going to combine this print with PLA combinations, with spray painting and include LED lighting in the design.

Degree of Difficulty: High - this print design is going to be the first layer of the print, with a combination of as much as possible additional features.  The intention has always been to push this student who has shown talent to apply himself.
Size: The print measures 120mm across.   The print base is 10mm thick.   The tallest of the towers for storage of stationary items is 90mm high.    The smallest of the towers is 30mm.   

Timeframe: Sixteen hours to print this design.   This is the base of the design and does not include the time for the additional features that are going to be added.   Given the scale of the print this is the minimum sort of timeframe possible with this technology and hardware set up.

What we would do differently/next step for students: The student will be pushed to develop additional features and creative aspects of this design, not limited to different PLA, spray painting and adding LED lights to the design.
