3D Printed Christmas Decorations

Challenge: Student wanted to use a 3D Printer to create and design a personalised decoration for a family member.
Background: Student was new to the classroom, near the end of the school year (in New Zealand).  We had a new student who had no experience with 3D Printer and wanted to show the possibilities that the printer could be used to create something.   The student had mentoring from another student, both of whom are ten years old.  The creation process was simple using the basic template from the main Tinkercad interface.  The photos shown with the print show the print prior to any 'clearning' of minor excess PLA.    The lettering was sunk into the base of the design to add detail to it (it also has at times been reversed and raised up, but the sinking into the base generally looks better in our students opinion).  The teacher had no input into the process or the design.
Degree of Difficulty: Medium - this is a students first print, but the basic design features can from the student and someone offering design advice.  We have created, and there are online tutorials available on how to create inserts and lettering, so the design is very similar to the 'keyring' and 'badge' design that have previously been published here on the blog.  Students could work independently on this task to complete it from the middle school (Y5 onwards).
Size:   The design measured 100mm across and was 120mm high.   The print was 5mm thick (this could have been reducded to significantly improve the printing time).   Variations on this design/theme have been created and posted on this blog previously.
Timeframe: Four and a half hours for the default setting with a 6mm nozzle and 20% infill.   This is standard Tinkercad/CURA settings for our Ultimaker 2.  These machines are now five years old although two years ago they were upgraded to Ultimaker 2+.   One would strongly suspect that a more robust machine would improve on the printing time considerably.
What we would do differently/Next Steps for students: None - this turned out exactly as required.

Further reference: In 2018 our students created Christmas Prints for everyone in the classroom and also buddy created with another student - this prints, ideas and designs are featured here.  Further examples can be located here and exemplars can be seen here

In total there are several pages of designs, creations and idea that have been featured on this blog (including the 'sleigh' design which was create dby students from scratch using the main Tinkercad Interface, as shown left.
