!!!!Rex:
Show off your i3 prints! All of my photos are of natural PLA printed at around 50mm/s @190-205 C and 0.15 to 0.3mm layers.
Here is what I've changed on my machine:

*guide tube for filament
*added vented panel to control box with 40mm fan
*eeprom settings updated with 400steps.. for z, lowered Y accel to 800, jerk to 17, increased z homing speed to 20.. probably more I cant remember.
*glass plate
*x axis bearings reduced to 2 and upgraded to lm8luu size (also shimmed bearing with paper to make them fit TIGHT in bearing blocks)
*x axis bearing blocks trimmed to clear belt. I went ahead and trimmed both of them on both sides to reduce a little mass
*z axis dampers installed
*nuts added to build plate adjustment screws to lock in place
*build plate holes slightly enlarged
*removed x and y axis tension springs and re-tensioned
*increased x axis belt bolt length to 25mm to clear bearing block

Still to do:
*swap out filament drive gear with MK9 style
*add another fan to electronics box
*change part cooling fan duct to plastic for reduced mass
*add angled LCD panel

Here is what I purchased online:
