Voron V0 Estimate cost

Here is my running total for the cost so far... Quite a bit more than the US$400 estimated. But I am using genuine Mosquito, which is around US$250 and using genuine Bondtech which totals around US$50. Please note that I am using a 24V power supply design, with no main AC heat bed.
