Summary

Here is a base for the 5W Creality laser that lets you add a 5010 blower fan to more effective capture and extract the laser engraver fumes. Level this like a typical 3D printer, with a small gap between the bottom of this plate and the item you want engrave. It is a smidge shorter than the "leveler arm" that originally comes with the laser.
The 5010 blower will generate a nice cross breeze that will whisk away most of your fumes to the back of the module. This should fit tightly onto your module, with little tape necessary.

Added bonus: This serves as a protective measure for the eyes by substantially reducing the visibility of the exposed laser. For enhanced sealing, consider the application of additional tape or foam around the base.

I also modded the air assist from https://www.thingiverse.com/thing:5525519 to redirect the cooling fan's air towards the laser beam. The laser has never felt warm during 10 minute engraving sessions, so why add more fan when original fan do trick?

NOTE:
Using the 5W laser at 100% power will generate too much heat and melt the base. For wood coasters, 40% was sufficient for me with decent extraction.

How I Designed This

Sketchup

Sketchup 2017, I will someday learn how to use Fusion 360 effectively.

I created the design in Sketchup, exported the STL and imported that to Fusion 360. There I repaired the mesh using the "Wrap" option, and exported the model to Cura. Sketchup files must very clean and perfect for this to work, otherwise there will be unwanted filled holes.

To better extract fumes

Fume extraction

I recommend using Hilde3D's 40mm fan to 22mm CPAP adapter and buying a $6 CPAP tube from Amazon (or ask anyone you know with sleep apnea if you can steal their old tubing) https://www.thingiverse.com/thing:2801576

I bought this fan from Intex: Intex -Quick-Fill™ 120 Volt Deluxe AC Electric Pump (QuickFill 110). It was $14 on amazon at the time, and was the best fan that produced the airflow needed at the end. Anyone who finds a more powerful blower-style fan please let me know!

THOUGHTS:
I tried using an 80mm fan and a big 4in fan from Amazon, but neither generated the airflow necessary to actually SUCK the air out from the chamber. You could try a vacuum pump, but I wanted a solution that was under $20USD, and that Intex Quickfill has been doing a good (but noisey) job. The small room the engraver is in still smells a little smokey after 10-15 minutes, but that quickly dissipates if the window is left open.

I've added that small 80mm fan to the Intex, and it can definitely run longer than 10 minutes. The center of the face's vents has a ring that better allows air to flow onto the motor, and the side gaps for air dissipation. This fan is rated for 10 minutes on/10 minutes off for cooling, but I've been able to run it for more than an hour with a small 80mm fan cooling it. It is barely warm to touch after 1hour of running.

Below is an example when you run the laser at 100%, and the soot the builds up after an 1+ hours of engraving wood
