So I started designing the strap in cinema 4d, but made a little mistake. (it’s a good thing I prototyped first) it is big enough to store the bluetooth module, but not big enough of the flora itself!
The overall design of it is great, I printed it on PLA using the ultimaker 2 extended 3d printer, but the final product would be made from something called ‘ninjaflex’.
Ninjaflex will be great because it is super flexible and child friendly. Obviously when making a product for children it has to be safe and durable. Ninjaflex would make sure that the modules and components inside would be safe but also unnoticeable.
