A modular warp weighted loom, with many options. Loom can be made to stand vertically or lean against a wall. Slots and arms all come in horizontal or tilted orientations for a variety of angles. Pieces come with or without holes for locking pins. Bar comes with or without holes for warping thread through.

All I did was separate it into 3 roughly equal sized pieces. Ideally someone would make a version that fits together with tabs, but this one is just cut flat. I'm planning on trying to glue the pieces together. The original wouldn't have been printable on my machine.

Some prototype Rhythm Bones I designed in TinkerCAD, and a version with a shaker attachment!

I made the shaker a separate file so it can be printed in a different material if you want. Just wait till the shaker is roughly halfway finished printing and then drop some sand or whatever in the cup mid-print. I used chopped up paperclips.

It maybe ought to be printed at a pretty high infill or else it'll be too light to play very well. On the other hand, you could maybe get some neat resonant properties by messing with the infill amount and pattern.

In playing, I've found that you can hold them either so that the plain bone hits the shaker, or so that it hits above the shaker. Either way produces a different sound.

V2 EDIT: Ok so I went back in and modified some things. I looked up some formulas for designing ocarinas, and used those to change the total volume and the size of the embouchure hole. Now with all the tone holes and the ends closed, it should do C5. In the process I made it shorter and thicker. I also changed the locations of the tone holes a bit, but not their size, or in any accordance with what note they produce.

Questions: Are you supposed to be able to completely close off the ends with your thumbs? I'm not sure that you can with this version, it might be too wide. Do the calculations for an ocarina of equivalent volume work for a koudi? Would the calculations for a normal flute be better, or worse?

------------------------------------------------------------------------------------------------

I didn't see any designs for a koudi (口笛) on here, so I tried throwing one together myself. This is just a rough draft to see if it even works at all, so please forgive the callous disregard for proper dimensions. It might be terribly inconvenient to hold properly, and it isn't in any kind of tune at all. I also tried to put more of a quena style labium on it because I just like that. The bore also tapers just slightly towards the very ends.

If it works, I might try to refine it by:
Using a more appropriate length to bore ratio.
Positioning the tone holes more ergonomically.
Sizing the embouchure hole and tone holes correctly to put it in tune.
Giving it more of a conical bore, in both directions just to see what that does.

I like knitting, math, and uplifting the proletariat.
