3D Printed Student Business Projects - Part Two

Above: Conditioner holder with lid.

Challenge: For students to produce a container/packaging for a classroom created business project.  The container needed to be able to hold liquid or cosmetic products.
Background: This is the final draft print of the classroom set designed described previously.  In these two examples students were looking to create containers that would hold samples of conditioner and lip balm.  (the cosmetics were to be produced seperately in the classroom and this is the sample box).
The students concerned were a Y4/5 classroom - nine and ten year old students.  This was their first 3D Print designs, which were created by students using Tinkercad, for the first time. Students were producing a prototype with a base and a lid, and experimenting with the lid being able

to be dropped into the base to seal the container.
Level of Difficulty: Medium - the issue consistently with this set of designs and prints was the lid.  The two lids in the case of both of these prints were no exception.  In both cases students had designed the lids without due consideration for a reduced inner lid which would allow the lid to drop into the base.  In the case of both of these designs students are going to re-design the lid and drop down the size of the lid insert so the base will work with the lid clearly in place allowing the concept to be successfully completed.
Timeframe: The heart shaped box was two and a quarter hours, the taller box featured above was five hours (both print time included the lids both printed at the same time.   This was on the normal print setting, with additional rafting to support the inserts.
Size: Right - the heart shaped box has a width of 6cm across a height of 2cm, the lid being slightly smaller.  The larger container had similar dimensions with the exception of the height which was 8cm. The width of both prints were 5mm and was above right from a size perspective.
What would we do differently: The boxes/containers need to have the lid reprinted because with nearly all other objects in this set the students underestimated the need to reduce the inserts allowing the lid to drop into place.  The students as noted are going to redesign the lids and re-print them reducing the inserts, the bases are remaining, so overall the prototype succeeded in meeting the breif.
