A 120mm fan grill for your ROG PC build. Two pieces so that you can have two colors using a single extruder printer that you can easily glue together with superglue. Mounting holes are for PC case self taping fan screws or metric socket screws can be used as well. Any good PLA or PETG works with no issues. No supports needed. You can use a brim, but it was not necessary for my printer.
I have used 0.2mm layer height for the first 3mm and then switched to 0.1mm layer height for a better top surface finish for the fan grill base.
