I think we should focus on making one general size pot working for now. Then we can work on variations, because the best solution for this would be to design a few different sizes on Fusion 360, this way we can scale the tank/pot without scaling the part holding the electronic. Maybe we could do a parametric stp file for people to play with but not sure if easy to do with this design.
Not too sure on where you can help, do you have any idea why R2 is 270 Ohm? I’m still wondering about this, I know it’s the mosfet gate resistor but I did not have time to search how it could have be chosen. Maybe you can help here? This way we ensure all components are well chosen.
@konig how did you choose the size of the hose connector? I see they have a 5.4mm diameter.
We might have to shrink them a bit because the pump connector is only 3.5mm.
This would allow to use only one PVC tube of outside 5mm inside 3mm for a tight fit. And it should also fit the t-connector. What do you think?
Not sure if this would print okay though. I guess I need to do more test prints.
