An adapter to go from a 75x75 mm VESA mountable case to two DIN rail brackets, so you can mount the case onto a DIN rail.
The DIN rail bracket I created this for is mmuellerphoto's excellent heat-set insert DIN rail bracket model (the one with 52.5mm hole spacing). My adapter screws onto two of these brackets next to eachother for added stability.
I sized this adapter to perfectly center my Raspberry Pi 5 PoE NVMe Case | Waveshare/Pimoroni for optimal horizontal space efficiency, but it should work fine for any other 75x75 mm VESA mountable case as long as it doesn't stick out too much. Other cases just might not be centered. Feel free to remix my model though!
Alternatively, M3 screws/nuts will do in a pinch. Though you might then need oversized M3 washers (DIN 9021) to cover the M4 sized hole sufficiently.
