MakerBot Replicator 2 Users

I'm trying to print some novelty jewelry with a lot of flat topped, narrow parts that I can't seem to get complete roofs on. Any suggestions? Parts are less than 3mm wide. Pic attached.

Hi guys, I fond this incredible deal on a used Makerbot Replicator 2, but it needs a new extruder setup. https://philadelphia.craigslist.org/ele/d/philadelphia-makerbot-replicator-2-3d/6787714578.html This one is a stock replacement, bu it is pretty pricey: https://www.amazon.com/Makerbot-Replicator-2-Extruder-Assembly/dp/B01CTURODY/ref=asc_df_B01CTURODY/?tag=hyprod-20&linkCode=df0&hvadid=312268245240&hvpos=1o2&hvnetw=g&hvrand=4696187114519528164&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9007435&hvtargid=pla-571310760175&psc=1 I was wondering how easy it would be to convert it to a bowden setup if any of you guys have ever done that, or if sonething like this could be modified to work: https://www.amazon.com/INBBOX-Assembled-Extruder-MakerBot-Printer/dp/B07FM4YWHP/ref=asc_df_B07FM4YWHP/?tag=hyprod-20&linkCode=df0&hvadid=249308200959&hvpos=1o20&hvnetw=g&hvrand=4696187114519528164&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9007435&hvtargid=pla-583149150216&psc=1 Thanks!

I had an extruder that flowed PLA below the heater and coils. What happened? Can I get parts? I broke some of the wires the head of the Smart Extruder+ of a 5th gen. Am I in the right place or is there somewhere else I need to go to get help? I am fairly new at this and not sure what I can do.
