I’ve done a ton of mods to my pair of ender 3 pros. A few are aesthetic, some are to fix quality control or design issues, and others are for quality of life improvements or to make some part of the process easier. Everything is done through trial and error and printing long enough to learn all the quirks of your machine.

Here is the stock version for you to compare,

and here are a few pictures of my setup, sorry if it’s hard to make out whats going.

I’ve named them Blue and Yellow, Blue is the one with Spider-man riding the extruder gear. Both printers have had the plastic extruder arms replaced with the red metal ones as they break down over time. I’ve added glass beds and reinforced springs because of commonly warped beds and weak stock springs. I moved the filament spools to my pegboard to reduce shaking when printing. Corner braces are there to support and to make sure the frame is square/level. I changed the belt tensioners on both to make it easier to adjust the belts. Both printers have had their motherboards upgraded for speed/noise/etc. and they’re controlled by a raspberry pi running klipper.Though they differ, I have also changed the hotends on both printers. All this to show how much is involved in something like this, don’t get me wrong, some of these mods were optional but I am someone who is constantly calibrating and trying to get the most out of these.

If anything take a look here at what other people are making for the ender 2.

Honestly if you’re just trying to print and have the money, go for the Prusa. If you like to problem-solve, figure out how things work. and have the time to learn, try out an Ender! hope this helps~
