Arris DOCSIS - Cable modem - 1RU rack mount

prusaprinters

SummaryI've got a small networking rack, where my router and switch are located. I've also got an NBN HFC modem, (a DOCSIS cable modem), this is produced by Arris for NBN Australia, but their enclosure is used across many different product lines. The 3d print snaps onto the top and bottom of the modem, and with some screws, and a rack blank plate makes for a robust rack mount for the unit. Parts Required1x 3d prints for Top/Bottom Mounts4x M3x8mm Socket Head Cap screws6x M3x8mm Flat Head Hex screws10x M3 nut1x 1RU blank plate: Pulse RPP1 (~$4AU Element14: 3371439) Assembly InstructionsPrint Top/Bottom 3d-printed partsPerform test-fit on modem, parts slide into the front, and then lock at the backDrill + Countersink 6 holes in the 1RU blank plate, be careful not to drill through!Install M3 nuts in 3d print, helps to use a very-small dab of glueClip parts to modem, install M3 screws in the back to lock mounts to the modemInstall flat head screws through the 1RU plate.Install into rack Printing TipsI used a 0.35mm profile with a 0.4mm nozzle. Since these are largeish parts.To get the best possible hexagonal pattern on the base of the prints, I adjusted prusaslicer extrusion width for the first layer near 0.6mm, until the hexagons didn't have lots of little tiny fills of extrusion. They'll look nicer if they're made up of single extrusion lines.I increased the bridge flow rate on the 2nd layer with a height based custom modifier. I found a value of 1.4-1.6 worked nicely from the default 0.95. Remix IdeasLight-pipes for status LEDsExtra spot on rack mounted plate for keystone RJ45 jackFan for modem
