A friend of mine "automated" his infusion pump (not diabetes) by 3D printing an arm and actuators attached to the physical buttons of the pump and controlling that remotely. Basically most actions consisted of automated sequences of button presses in the correct order. How feasible is this for an insulin pump? I know it adds bulk to a device that has to be worn constantly and inconspicuously but it may be a worthwhile trade if you can't find a compatible pump. As long as it can be controlled by the wearer's finger it should be possible to automate it with an "artificial finger".
