I made a Rackett! After some searching, i found some blueprint online (https://archive.org/details/a-step-by-step-guide-of-the-construction-of-a-renaissance-rackett-manual) and was able to build a model from those in Blender. Made a few test fit prints, did a few more prints, and a dozen or so failed reeds later, i have a functional instrument!

Here is an example of it being played

As this is a wind instrument, the tolerances on the pieces that fit together needed to be tight to prevent air leakage. My printer is well calibrated, but not obsessively so. While some of the parts fit tight, they do wear down and loosen up a little bit, but this has yet to cause any tone issues with this rackett. I would recommend against filing pieces down to fit better as that might allow air to leak and will ruin the sound.

The reed for this also makes a HUGE difference on the rackett sounding like it should, not making any sound at all, or sounding like a bin of dog toys being ran over by a steamroller. I've included a reed guide and a step by step ‘How To’ to make your first garbage reed including a troubleshooting section to at least help make this process a little less wasteful than what i went through. Still though, expect to probably spend as much time making your first reed as it takes to print this.

I have also included the original blender files, which include the body with curved finger holes, an alternative straight hole version (which is more traditional for how this was originally made), and finally a body without holes cut into it at all for people who want to experiment with them. I figured including the blender files would help other people remix and help make this instrument more useful and generally better. Lets start a Rackett Revolution and revive this sweet instrument!

Have fun! Go serenade the world with the wondrous sounds of this renaissance rackett.

If you are printing and selling this, all i ask is that you have your customers take pics and post makes here on this page. I just want to see other people playing and having fun with it!

(All parts were printed on the K1 max using the default high quality settings. Only change was to infill which was changed to gyroid for a more organic infill to accommodate the acoustics of the instrument. No brims, rafts, or supports needed. Just make sure you have good bed adhesion and you should be good to go!)
