The redesigning of the enclosures is now complete and the new STL files are available for download on the project website https://www.softrobotics.io/flowio under chapter 2. The latest enclosures have been greatly improved on their visual aesthetics and functional characteristics compared to the previous version.
- The base for each module was completely redesigned to make the attachment more secure.
- The need for supports during 3D printing has been greatly reduced, making printing much easier and even saving some material that would normally go towards support structures. This also reduces the print time slightly.
- The bottom edges are now also filleted just like the top edges, which was previously not possible with the earlier design. This makes the device much more comfortable to use when being worn.
- The new enclosures are 0.75mm taller.
- The battery for the medium pump module now goes below the pumps rather than behind them. This enables us to use the same kind of battery as the one used in the main module, thus reducing the number of unique parts. As a result, the medium pump module is now almost 7mm smaller in length, but now the entire device is 0.75mm taller - which was a great trade-off.
- The added height of FlowIO now allows for a 3D printed separator to be added in between the battery and the valves in the main module, which greatly increases the safety of the device by preventing heat from the valves to be directly absorbed by the battery.
- Because of the dimensional changes, the new enclosures are not compatible with the old ones, so if you have a FlowIO device already and you want to upgrade to the latest version, you should 3D print all the parts.
