I have a few mini-pcs, specifically HP EliteDesks, and raspberry pi 5s. Presently they sit scattered on server shelving. Workable but suboptimal. Deciding to address this, and owning a 3D printer, I decided to print a small 4U server rack to consolidate the hornet’s nest. Thankfully, others came before me so there were plentiful options to choose from, especially in the 10U size. But I don’t have 10U, the shelf is a little over 4U bottom to top. So the hunt was on for rails that would fit. After a few google searches, I found a model on printables. Six hours later, I had rails.
Today is assembly day. Will let you know how it goes.
