Modular 19 Inch rack mounting system
prusaprinters
<p>I had the need to mount some Dell 7090 Micro Form Factor PC's in a rack. So I designed this modular mount, which allows them to be mounted, and to store the power packs to be sides of the units. It also has a spot to mount a power board. These are all held together with the ~8mm pins of various lengths.</p><p>These all fit nicely within a 19" rack. I've mounted these with RackStuds - but I am working on a potential 3D printed mounting system, to avoid the use of cagenuts.</p><p>The Powerboard used is a HPM R105 - <a href="https://www.amazon.com.au/R105-Power-Board-HPM-Fitting/dp/B0786Y5K5W/ref=sr_1_8?crid=1AB2ZEIVOI4HX&keywords=HPM+power+board&qid=1651055591&sprefix=hpm+power+boar%2Caps%2C235&sr=8-8">https://www.amazon.com.au/R105-Power-Board-HPM-Fitting/dp/B0786Y5K5W/ref=sr_1_8?crid=1AB2ZEIVOI4HX&keywords=HPM+power+board&qid=1651055591&sprefix=hpm+power+boar%2Caps%2C235&sr=8-8</a> </p><p>All parts were printed with 6 perimeters, and 15% infill. All a parts are printed ‘face down’, partly so that I'd get the texture from the textured plate, but this is also the optimised orientation to print everything support-free.</p><p>The 6 perimeters are what I'd recommend, as it tends to make the parts the strongest.</p><p>The pins can be printed standing up - I printed them with 3 perimeters and no top/bottom/infill. This made them easy to press-fit, but you may need to adjust the scale +/- 1% depending on your printers tolerances.</p><p>Fusion360 file has been included - so feel free to remix this to suit different devices.</p>
