BTW, the 1cm cube yields a quoted price of $1.82. But what should it be? The old formula: $1.50 base price plus $0.28 per cm^3 of material and $0.21 per cm^3 of machine space. Material space would be 1cm^3 and machine space would be about 1.728cm^3 so estimated price (wsf) = $1.50 + 0.28 + 1.728(0.21) = $2.14. There appears to be a pricing error that is advantageous to the customer when this error happens, assuming the pricing formula has not changed since earlier in the year.
