Telescopic 7" drum (darbuka)

It's a telescopic 7" drum (darbuka). The drum head is not 3D printed but was purchased from thomann.de (shop link: https://www.thomann.de/fi/thomann_7_darabuka_head.htm). I'm not entirely sure how standardized the drum head dimensions are, but it fits perfectly with the one sold by Thomann. In addition to the drum head, you'll need 6 M4 nuts and bolts. I used locking bolts in mine, and they seem to work great.

I printed mine from PLA, but I would imagine this could cause issues if left in a place where temperatures approach the glass transition temperature of PLA—so, I recommend using a different material. It's best to print the entire drum from a strong material, but if you prefer, you could print just the rim from a stronger material since that part undergoes the most strain.

All in all, I think the drum functioned better than expected and is quite playable, even though I'm not that experienced with small darbuka-style drums (I'm more accustomed to playing large djembes). I could also scale up the model for a larger drum head, but since I didn’t have a large enough printer to make a drum like that, I kept it at the 7" scale and used the affordable Thomann drum head. If you have a larger drum and want to make a bigger one, let me know, and I can scale the parametric CAD design to your required drum head size.

One aspect of the playability of this drum is that the individual segments don't lock into place when fully extended; instead, the drum remains loose. This characteristic makes it an interesting fidget item but may slightly complicate playing. Depending on how you position it between your legs, you might notice the segments "rattling." I find this sound quite appealing, reminiscent of a snare drum. However, if you squeeze the drum's topmost part between your legs, the rattling significantly reduces (unless you strike it with considerable force).
