Ender 3 Pro Beginners Guide - Part 2: Printable Upgrades

Printable Upgrades 

One of the best thing about Creality Ender printers is that, it has a huge community and there are many printable upgrades that you could use which increases the quality of your prints. 


Filament Holder 80mm with Bearings
For this part you need to buy 2 bearings. I do think that a filament holder with less friction is a must for quality.  

Also i printed the roller part from a remix(not the one above) which is a curved one, which helps oddly shaped rolls run without an issue



Filament Guide 
If you hang your filament on the top of your printer, use a filament guide to guide the filament to extruder with minimum resistance: 

If you have enough space, print side spool mount to the filament holder, so that filament could stay right next to the printer attached to the ground bars. This way filament roll movement would not create vibration. 


X Belt Tensioner

Display LCD PCB Cover
LCD PCB is not closed and a cover will help  not to damage it or cause a shortcut. I printed the one below which also allows adding a bipper silencer also

Display Ribbon Cable Clip 
to attach display ribbon cable to metal bars, you would need clips. IF you also wanted to print a drawer, either find a one that has empty space for ribbon cable clips, or do not use the clips and take the cable below from the drawer. 


Power Cable Clip
to tidy power cable at behind, you need deeper clips than the ones for ribbon cable. You could use the below clip:

Cable Chain for Z Axis
Extruder, Z axis stepper motor cables sometimes hit the print table and can tackle around. So it is a good idea to tidy them with a cable chain. People sometimes use cable chains for both hotend to extruder, table heat cable, and exturder-z axis cables. These chain cables are a bit noisy so i think only printing it for extruder-z axis stepper motors are enough. Below is the picture of my device

Extruder Knob & Metal Extruder Cable Clip 
If you also use metal extruder (which i suggested in part 1 also), below clip helps to attach the power cable of the fans to the extruder. 


Feet Noise Dampeners


For Noise dampening please watch the video below, it is a much more better solution but you need to find a concrete (like..). block to lay under the printer.


Z Axis Spacer

Z Axis Lead Screw Stabilizer
I was thinking of using Z axis lead screw stabilizer but than in a comment i read that,top of the z-axis is MEANT to be free-floating to IMPROVE print quality and so i do not use it. Here is the video:

Fan Duct 
For a better print quality, cooling is really important. If you do not want to upgrade to 5015 fans and use stock fans, bullseye duct is one of the best fan ducts for ender3 pro. If you are willing to upgrade fans petsfang is the newer model.


Read the thing details carefully since there are many files and versions. Below link shows what to print:

Installation videos:  
 
There are direct-drive modes compatible with bullseye fan also but i think direct drive modification is not for a beginner, you will need a bit more time have experience before going on to direct drive. 

In the video below, you will see that bridging quality becomes better with Bullseye duct

Tool Holder
I prefer the above one, since it is not on z axis and not adds any space to existing usage. 


1.75mm Filament Clip
