I’ve been having a lot of fun printing prototype pieces for a potential high altitude balloon box (more on that another time). Unfortunately this is a lot like the old days, when printers replaced typewriters. As I made corrections to a document, I’d reprint it. WYSIWYG was not really any help. The paper copy was always a little different. Suddenly I could go through reams of paper perfecting a small document. Unfortunately, I use my 3D Printer the same way, exploring new ideas and finalizing fits.
