I want to give you more money! When you're ready to open up the Kossel Pro to the general public, I'd be interested in buying: Extra glass for fast swapping/spares. Another heat cartridge with the 2-pin connector so I don't have to wire my own (again.) Additional ring-terminal thermistors for trying different hot ends with the OBKP effector Thermistor potting compound. Nozzles of different sizes. I know you're finishing fulfillment and working on the polish, tweaking, etc. but my credit card is ready for all of that - especially the top two.
