Keyboard X-stand Braces

This bracing system is meant for X-style keyboard stands, like this old Quik Lok brand stand shown below. It should work for other stands of this style as well, which have something close to a 30mm or ~1 3/16" diameter tubing used for the top and bottom ‘rungs’. The 4 identical 3D-printed pieces slide over the ends of the two plywood lengths (painted black to match) and get screwed into place. The two completed braces snap into place on each side of the stand, under slight compression, and prevent the stand from deflecting when playing. I chose PETG for my material, because I wanted the flexibility, strength and resistance to heat. Although, the braces will obviously only work at a given height setting for the stand, I almost always use the stand at its lowest setting anyway. Once installed, the wobble is completely gone, and the stand feels rock solid!

The printed pieces fit over standard ½" furniture-grade plywood that you get from the home improvement center, ripped to 1.2" in width on a table saw:

Then you cut the plywood pieces to whatever length is needed for your particular stand. The 3D-printed pieces have a wall thickness of 2mm, so you need to cut the wood 4mm or 5/32" shorter than the distance that you're trying to bridge between the top and bottom ‘rungs’ of the stand. (I also wanted a little compression when snapping the braces into place, so I took a bit off that 4mm figure.) For me, I cut the wood pieces to 23 5/8", which worked well for my stand. If you're unsure, just cut the wood pieces a bit longer than you need and fine tune the length by trimming as needed. Then you slide the 3D-printed pieces onto the wood pieces to mark and drill holes for #4 ½" long flat head screws which hold the pieces on.

In case you would like to keep the braces with the stand when you fold it up, I also designed a holder piece that the braces can snap into. The holder piece attaches magnetically to the stand, using this strong neodymium magnet (found on Amazon here:  https://a.co/d/5pdOk2z ) which fits into the pocket as shown:

So the bottom half of each brace can unhook from the bottom rungs of the stand and snap onto the holder piece, like so:

So that's it, enjoy!
