3k before tax and 2k after, is 33%. Not 50%. 33% is normal for a medium-high earner in Europe.

Infinity numbers are weird. .9999… is 1 as long as there is no end. Same as 0.000… is 0 as long as there is no 1 appearing. 1-0.999… is 0.

Have you printed that blue spool before at that temp? Do you use any cooling?

My ABS kinda looks like that if I forget the fan on, or have a too low nozzle temp.

This is very well thought out.
