Multiboard Threaded Keyboard Holder

Just a remix of FredvomJupiet's Keyboard Holder for the Multiboard. Their model uses a Multiboard plug style connector, and it works fine for most lightweight keyboards. I have several keyboards, and thought it was a beautifully designed piece of work. Some of my keyboards have aluminum shells, though, and are around 4+ pounds. I'm not confident in the plug in style connector to handle that weight. I modified their work a bit to have holes spaced apart to fit medium threaded Multiboard threads that go into any large thread with medium thread holes. I printed with supports enabled. I recommend printing the first layer slower than normal and to thoroughly clean your print bed. I print my first layer as one wall to ensure that layer is perfect. Since these are threads, you will want them to print relatively problem free. I printed this one in PLA Matte, but I would recommend the shelf be printed in PETG if you have a heavier keyboard. I noticed some flex to it with the matte PLA.
