To maximize the model’s usable area, it has been designed to be foldable.
Both the right and left sides of the model can be foldedup to form an enclosed box. A benefit of this design is that it protects all models, sensors, andother components from outside damage.

Since this was the first prototype, there had been no closing mechanism designed yet.
MDF was used as a base material and only two layers of wall thickness.
The biggest learnings had been, that MDF is terrible for long term usage and that the cables need to be protected with ample routing space between the different parts ot the box to reduce tension.

With the second iteration the switch has been made to use acrylic glass. This not only improves stability, but also makes the project interesting to look at, as all the cable routing is now visible.
Further the wall thickness has been increased by adding a small 1mm clear layer to protect and enclose cables running through the wall.
As for the bottoms, there a 4 layers to route the safely cables while maintainung structural integrity.

All panels are glued up, however this posed problems in the long run and led to visually unappealing results. It also made maintenance very time consuming.
The model relied on hinges to be opened, magnets were introduced as a closing mechanism.
All 3D-models were redesigned and the electrical layout was made anew.

While working together with UofA it became clear that some aspects of Version 2 need to improved on before user testing can be done.
However, since the technical upgrades and the new layout have proven to be sustainable, there was no need for a full redesign as Version 3.
Replaced the old hinge with a cloth hinge to avoid supply issues and reduce the amout of proprietary hardware.
Removed all glue-ups to make the model repairable. Now everything can be screwed together with 3-D prints, that have melt-in thread inserts.
We simplified production, so now it only requires:

• a 3D printer
• a laser cutter
• a Soldering iron (and soldering equipment)
• M4 bolts
• Melt-in thread-insets
• Basic hardware as per BOM
