1/2" G BSP finger nut for Securing Tap to basin

thingiverse

This is a versatile 1/2" finger nut for securely fastening a tap to a basin. Its precise dimensions are in line with ISO228 standards, but to accommodate my specific tap, I had to print the design 2% larger in both the x and y axes - a decision that proved correct on the first attempt. Scaling the z-axis, however, requires caution, as it would alter the critical 14 threads per inch (TPI) count of the nut. To maintain its functionality, a uniform scale must be avoided at all costs.
