3D Printed Bookend - Advanced

Challenge: For student to create a 3D Printed personalised bookend for their own use.  As an additional challenge students were asked to combine a minimum of two different PLA print colours for extra effect.
Background: This student (who is nine years old) has been producing prints consistently for the first time this year in class.  She has produced a number of prints that have featured on this blog and we have been looking at opportunities to extend her and challenge her.  The initial design and print of the bookend featured here was red, featuring her name.   During the removal of the '

rafting' of the PLA for the design, the 'r' became removed from the design.   The student then had to design a replacement letter of the same size and design of the original,  except this time in black.   The bed aspect of the print, which was the second major feature was also sized to complete.
Level of Difficulty: Medium.  We are looking at ways to extend students in a practical way with the 3D Printers that will produce a print that will be workable, have a practical purpose and produce a print with a finish.   Obviously the degree of difficutly could have been increased by having multiple letters reprinted, potentially in multiple colours, and the bed could have been designed from scratch (as it was it was a created print sourced from a 'Tinkercad' search.
Timeframe: The base of the print, which was the red with the original lettering was eight hours.   The black addition of the bed and the letter 'r' was a further four hours.  The combined print in this case was twelve hours.   The block part of it, with the base, could have been increased with additional weight and design.   However as it was the design met the expectation of the student.
Size: 130mm long, 80mm wide and 5mm deep.   The end of the print was 80mm wide, 100mm high and 10mm thick.   The lettering of the students name was 25mm high.
What we would do differently: Other than the student looking to mix up more of the PLA between the two colours, the design, being individualised and unique met the students brief and was extremely successful.
Next Step for the Students: We have had discussions with students about mixing up the PLA colours with the different prints being run.  The challenge is for ways to integrate this into different print designs without compromising the designs themselves.
