This is a simple 1U rack support used to fix any type of components in the rack. It provides a flat surface for placing devices that do not have their own rack mounting brackets. In this example, I will use it as the back support for this 10-inch rack mini ITX chassis model:https://makerworld.com/es/models/1523227-3u-10-zoll-rackmount-mini-itx-dual-gpu

The size of the support surface is38 mm x 80 mm。

The original idea came from:https://www.printables.com/model/1298178-simple-1u-rack-mount-holder-or-shelf
