Under-Desk Keyboard Holder

thingiverse

This is a solution to hide away a keyboard (for example) if not needed. You have to undo some screws on you're synth (YAMAHA CS1x in my case) for attaching this mechanism to it. So, if you're not into this, you better skip that thing ;) If you're synth has a solid base and is one of the older ones, please continue... *** what you need: *** - 8x M8 threaded rods (in my case 31 cm long) - 32x M8 Normal-Nuts - 2x M8 Hut-Nuts - 34 M8 washers - 4x M8x40 Screws with a flat hat (the hat is facing to the synth as you see on one of the pictures) - 12x Screws for mounting your prints to your desk-plate. But be aware, to long screws might destroy your plate!) - 4x Screws to mount your synth to the "ARM" structures. You can edit the length of the "ARM" structure in the .scad File with Parameter "auflagelaenge". I just drilled holes in the print (not the keyboard of course) for the keyboard without programming a hole in the scad file. You need to just uncomment the code below "//ARM" and compile it to export a separate stl file in openscad when you need a different length. The structure itself can easily arranged to the screw-position of your keyboard due to the threaded rod and nuts. - for fanciness: 2x bearings (688-2RS / 8x16x5mm). But you don't really need them. - lubricant *** tipps: *** - loads of infill ->80%<- cause you're print might hold quite a load, specially if you push you're keys hard ;) - cut the threaded rods at the and when positioning to get you're needed length. - I put the original (shorter) keyboard screws in a zipper-bag and taped them to the holder for recovery. There is a vid for explanation. Use some lubricant on the slide-mechanism cause its pritty tight there: https://youtu.be/IDDZiplEeQA
