Background: As part of the major sound lure project that are students are working on, one of the key issues is 'water proofing' - ensuring that the sound lure is able to be deployed but protected from the environment. This is another box in the series but this student wanted to use the 3D Printer to produce a lid that could be locked in place to ensure that the container was water tight and the lid would not come off unless it was removed. As shown in the photograph on the left the lid has breakable component parts that need to be carefully removed to enable the lid to be slid into place. With the lid then inserted into the gap created by the removal of the excess PLA the additional support for the lid as shown holds it in place. There is also an internal wall with a removable section to support a division between the battery storage and the speakers. The students were basing all these dimensions on the speaker/sound device combination that our students are presently working through. These dimensions reflected the design, shape and size of this sound lure.
Size: The box is similar to other designs in this series to reflect the size of the sound device. It was 100mm by 100mm square with a height of 60mm. The internal wall was placed 30mm from the end of the box to include the batteries as storage.
Time frame: Nine hours to print on the regular settings of nearly everything that we've printed over the last five years. 8mm nozzle (in some earlier posts this has been described as a 4mm nozzle but this was incorrect due to a misunderstanding. The infill is the 20% standard default. There was some adjustments made below.
