Well, there are ways to design things that depend on high accuracy and precision to work, and there are ways to design things that don’t depend on high accuracy to work.
An example from working with an electrical engineer years ago: he was designing a network to provide a bias voltage to each input of a differential amplifier, so he designed two separate resistor divider networks that required 0.01% tolerance parts to get both inputs to be close enough to have the output offset acceptable. The actual input bias voltage was very forgiving as long as they were the same, so I rearranged his four resistors into a single divider and fed each input through a resistor from that. I could use 10% tolerance parts and the output offset was still a tenth of what he was getting.
So, it might take some clever engineering, but I wouldn’t discount it as undoable (and 3D printing is getting better by leaps and bounds…)
I do agree, there is a whole lot of wrongness going on with this story, from the medication + dispensing method being tied to each other, to the design being funded by public money…
