Raspberry PI 19" 2U rack mount

prusaprinters

I had side mounted raspberries using this model. But at some point I've got too many RPis, so I've decided to creaate a proper 19" mount which should be easy made with as least print as possible.BOMThis model consist of several parts:Mounting bracketsAluminium extrustion rails10x20 square tube (2pcs), 450mm length12x12 square angle (1pcs), 450mm lengthModule handle with clipsModule RPi mount plate3x12 screws for clip assembly (2pcs)Bolts to mount RPi to mount plate (see note below)NoteThis model is intended to use with PoE HAT. But it's not mandatory (but there is no sense). I'm using waveshare one https://www.aliexpress.com/item/4001298160940.html so dimensions are made to fit it as single module. Other PoE HATs might have other dimensions RPi'nting & AssemblyRackMounting brackets should be printed on the most flat side (as shown in the picture), two symmetrical parts. This orientation will prevent it from cracking when extrusions will be pressed in while assembling.Cut aluminium extrusions to the length specified and press them firmly to the corresponding mount holesVerify that assembly fits to your rack, remove some extrusion length if neededNow you have rack itself assembled and installed.RPi MountPrint the clip. Check it fits well to the rack with satisfying click. I've printed mine with some brimPrint the RPi mount plate using this orientationModel has some closed holes for mounting hardware, use the drill or the bolts themselves to go throughUse the premade hole to attach mount plate to the clip with 3x12 screwsYou're done! Now you can clip your raspberry pi in and attach ethernet with PoE to power it
