@NeverDie Yeah, but when I priced out domestic places, they all wanted enough that the client just decided to go a different way. This was only going to be for a prototype, but even so, I got prices ranging from I think $10-50 per pin holder, and it was less than 2 grams of plastic each. I just checked again, and JLCPCB would do them for $1 each, and then $20 for quick shipping, and as low as $4 for the slow boat that takes a month. None of those options were very appealing at the time.
Digikey wants $13.66 each for this when I pick qty 10, so still not worth it for this project. Shipping with them is free, but I have no idea how quick they would be.
I also checked PCBWay, just for fun, and they quoted 1.24 at qty 10, for $12.45 total. Interestingly, the quote for 1 was $12.45 also. They wouldn't show an estimate for shipping without clicking the 'Submit' button and having a human engineer review the file for printability. Since I'm not actually going to do this now, I don't want to waste their time, so I don't have a total price from them for comparison.
As far as OP, this is a very old thread from 3.5 years ago, so I doubt that they still need help.
To fix, first clean the nozzle to look like new from the outside. Next heat up the nozzle to temp and apply pressure to the filament with your fingers, usually this will push through a clog. If you cannot manually push filament through, consider replacing the nozzle or entire hotend.
Reporting back: I have my BambuLab X1C printer setup and have printed with it for about a week. It's fantastic: it's fast, and the prints come out perfectly every time. Truly an appliance: it works with only minor setup straight out of the box. I'd say it's a quantum leap better than my Prusa MK3S, which I guess I should try to sell while it still has value.
