This is a print for a tablefan, its made for 120mm fans, with an additional file where you can mount your own design! The holes are 5mm wide and are spaced an even 102 mm (from hole center to hole center) so that you can make your own design to put onto it!

It is still a WIP for me, as I have not yet been able to print it due to my many other printable projects, but dimensionwise it should be able to work as I have used previously used dimensions for another project using a spare 120mm PC fan
