Summary

I loved Wafflecart's mesh filter, does a great job stopping dust but I wanted to use it for a 80mm fan so I decided to just model it up as an openscad customizer so everyone regardless of modelling skill can have a custom dust filter for their computer (or other project).

Use 0.2mm layer height

Try a coarser "Mesh Fineness" if the first layer is fusing together and stopping airflow

Holes are located at standard spots for each fan size (for example 105mm apart for a 120mm fan)

If the fan you want a filter for isn't included as a basic setting there are advanced settings to help you make any fan grill you'd like.

Don't try to generate anything over an 80mm fan using thingiverses customizer as the number of small objects created on Normal or even Coarse "Mesh Fineness" is so great that it will struggle to render, instead download and use openscad directly!

If you need help with anything or want any features added just let me know and Happy Printing! :)
