Hey there!
I replaced the hot ends of my two Ender 3 V3 SE and had to thus unscrew the fan. Thing is… the screws hexagon socket became rounded with just this one replacement. Out of 8 Screws, one went missing, and 4 are rounded.
As the fans became really loud after this replacement, I want to use this chance to upgrade to 4010 ones. Though these still require the screws that came with the printer. So naturally, I want to replace these screws, hopefully with some that are better.
Thing is… the screws, as I measured them right now, have a diameter of 1.9mm at the threads and a threaded length of about 11.69mm (I guess 12mm?), which would give it quite an unusual size. M1.9 screws aren’t even sold.
Am I measuring these entirely wrong?
What are the correct sizes?
