HDD 3.5 Stand x3 Plus Fan Support

It is a model designed to support three 3.5 HDDs using screws to a wooden or metal board. In addition, this model contains a support for a fan which includes a design responsible for redirecting the air flow towards the hard drives.
The fan is not necessary, the supports can be used separately but the use of these is highly recommended in case they are going to be used for very long periods.
I have also included the model without any text to improve air flow and to facilitate quick and easy printing.
