One of the issues I'm currently having with the car is that the passenger's door won't lock easily. And if it DOES eventually lock, it's almost impossible to get it to unlock. Now, oddly, this was not an issue until after I "renovated" the door. If you take all the new parts off, it locks and unlocks perfectly fine. In fact, if you just remove the little lock indicator surround below, it works perfectly.
It turns out that the 10mm lock pin fits a bit TOO snugly into the 10mm hole in the lock pin surround. I guess 40 years of sunshine and heat shrank the rubber a bit. Now I COULD just go out and get a replacement, but there's no guarantee that it won't have the same problem. In my mind, it's better to widen the hole to 11mm, leaving half a mil on each side... So, since I'm bored and waiting anyway...
I'll hooked up some TPU and turned the detail as far up as it's ever been. 0.05mm per layer. Not because it's needed, no... Because I don't know that I'll ever print a piece this small again, and damnit, I wanna know if it's worth it! If I had tried this fine a setting for, say, the HVAC surround I just printed, it would be a 30+ hour print. For this little 20mm piece it's under one hour. Including supports. There was a big ol’ booger on the top of the print, but a Dremel took care of it. Pics tell the story.
Lock works now. So onwards and forwards, to the hood!
