Why would I ever re-design a working part of a printer?
|It does look robust, but hard to disassemble! (Escher)|
By the way: there are really two main usages for a 3D printer: the obvious first is to print objects... while the second is to print replacement parts for the printer itself! Sounds weird, eh? "So what are you printing with your amazing printer? - Well, most of my time-consuming designs are printer part replacements!"...
Now back to the question: why shall I sometimes just re-design a part of the printer with no added value beyond the ease of manipulation?
