This is the result of a lot of experimentation with printable clamping mechanisms to hold two surfaces together tightly. This clamp design lets me insert and remove an object (in this case, the reeds for an accordion) and vary the clamping force holding it in place. I put up a detailed writeup on how to design these togs here: http://pocketfactory.org/?p=71, and this is really just a companion thing for that writeup. You're free to print my design, but I put up these designs with the intention of adding another tool to the toolbox of 3D printable mechanisms.
I recommend that you use my design and thinking (see my detailed blog post on designing togs here: http://pocketfactory.org/?p=71) in your own designs, rather than just print out the object that I've shared (unless you really want a reed block for a button accordion). This is more of a mechanism to be used in your own designs than an object in and of itself.
If you do print these designs, know that it takes a bunch of force to get the tog into the tog block. I'd insert it partway, and then flip it over and press the thing against the table with the heel of my hand to get the tog all the way in. It's an alarming amount of force, but hey--it works.
