The Best Creality Ender 3/Pro Upgrades and Mods

The Ender 3 is an amazing 3D printer. For the money, it's hard to find one that will give you better prints right out of the box. However, it's far from perfect.


In this guide, I'll show you the top must-have upgrades and mods for the Ender 3 and Ender 3 Pro—both 3D-printable and purchased upgrades/mods.


A note on this guide:

In researching this guide, I found a lot of others with massive lists containing every upgrade and mod under the sun—unfortunately, many of those upgrades are pointless wastes of time and money. So, in this guide, I'll cut through the BS and cover the most impactful items that will give you better prints while also improving your overall printing experience.



Upgrades and mods to 3D print

Below are the top 3D-printable Ender 3 mods and upgrades you can perform. Tons of other printable mods exist, but this is the core list that will give you the best bang for your print time.



Board fan guard

Before you print anything else, print this mod. The location of the mainboard fan is directly beneath the build plate, meaning bits of filament can fall in and damage the fan or board. The model is available on Thingiverse.



Filament guide

This filament guide holds the filament away from the feeder, allowing for a more consistent feed rate and less skipping. It snaps directly into the side of the upper support.



Cable chain

This cable chain is a must-have for preventing dangerous cable snags when the bed moves along the Y-axis.



Display PCB cover

This simple screen cover protects your Ender 3 display's PCB (printed circuit board) from damage.



Bowden tube fitting fix

If your Bowden tube has popped out of place or if you're having print quality issues, you might want to print these pressure fitting shims that will prevent your Bowden tubes from shifting or popping out during printing.



Beeper silencer

You've probably noticed how loud the Ender 3 beeps when navigating the menu interface. This beep can level villages and knock satellites out of orbit. This 10-minute print mutes the beep quite a bit, getting rid of that annoyance and protecting our countrysides and space assets.


 If you're using a 3D printer enclosure, I recommend printing these mods using ABS or PETG filament; ambient enclosure temperatures can cause PLA to warp and deform over time.
