Task: Students were supplied with the wood, with the inserted holes cut into the wood. This allowed students to determine the shape and design of the 'join'. The first print on the right was created without an attempt to measure the join, therefore the students were estimating without measuring. The second version was designed with measuring as part of the process, the students grasping the concept of measuring and then transferring the measurements to the Tinkercad program.

Issues: As noted as the fit was extremely tight anything that would create additional material would hinder the fit. The extra PLA at the base of the join caused it to require sandpaper to remove it.
Size: This varied depending on the print run. The first was 2cm by 2cm (as shown). The reprint was 1.5cm by 1.5cm and this completed the task as expected.
Timeframe: There were eight protoypes that were printed in one go - a combined time of 90 minutes.
Process: This was a challenge that was set by the Principal of our school as a follow up to the name plate challenge. Students were supplied with the wood for the join which they would eventually use to measure an exact size.
What we would do differently: This was again a simple introductry task that relied on the students ability to create and problem solve a practical task, it reinforced the students to measure accurately and then translate this measuring to 3D Printing.
