I've owned the Ender 3 for a few months now and have made a number of upgrades, both purchased and printed. Here's a list of what I have purchased and printed, sorted by importance/usefulness.
 
Purchased Parts:
 
Printed Parts:
 
Future Upgrades:
Spool Roller - One issue I've found is that the stock spool holder requires excessive force from the extruder to unwind filament. A replacement spool roller with bearings should reduce the friction significantly and produce more even extrusion.
Metal Extruder - A common problem with the Ender 3 is that it fails to maintain proper tension on the extruder gear, which leads to failure to feed and poor extrusion. An all-metal extruder has been known to fix the issue.
Have a look at the bulldog extruder. It has a much higher clamping force on the filament. It does require you to have Marlin or T3HD firmware installed.

The other one linked is really pricey for what you get, this one is 2.5x as many for less. It's the kit I've got, it works really really well. Order this at the same time
I use them for tons of my prints now, put a small M3 screw into the knurled brass fitting and hold the screw with needlenose pliars in one hand. In the other, press your soldering iron into the hex hole in the top of the screw (should be a short screw). This will heat up the knurled fitting and help you put it in straight.
Here's a couple photos of a couple of project boxes I made
screw set.
Probably could use either. The recommended ones fit right into the heat sink fan, another set might sit over the fan and need to be a little longer?
Above is a simple kit.
