This is a re-entrant speaker just like any basic megaphone, where you can attach your own inputs and casing. No support is required.

Other included models:

**Attachments**
- Simple hexagonal end
- Megablok attachment (3/2 height - You can use the half-height block to match with other full-height blocks)

**Speaker**
These (along with spacer file) are specifically designed for the parts salvaged from [this monaural earphone](https://www.yazawa-online.com/page/1341/) so that I can use the 3.5mm stereo mini jack as an input. This is just here for reference.

This is the remix of [Squishy Turtle by Jacob Stanton (link to the original)](https://material11.com/shop/squishy-turtle/).

This model has compatible top and head with the original models. I also added screw threading in case the original  H-clip warped out (which happened to my PLA prints). For assembly with screw, all components are included in this model, although if you prefer the original H-clip assembly, use the bottom and the clip from [the original link](https://material11.com/shop/squishy-turtle/).

Support shouldn't be needed, although you might need one under the chimney right on top of the head. Thread tolerance is modeled at 0.15mm. It worked fine with layer height at 0.20mm for Prusa Mini with Plusament PLA.

Head's shape is a bit wonky (as I'm still learning modeling) ..but I'll say it's a charming feature to add something organic to this machine-organism.

Update V2: Made tail more accessible, and tweaked a few minor details (slightly thicker chimney, roof protrusion towards front side, etc)

Probe that can be wrapped with cloth of 0.35mm or less to clean the Lightning port.

1. Fine layer height recommended for the probe part.
2. Use it with a microfiber wetted with isopropyl alcohol
3. Make sure the probe has gone all the way. One side has ribs on the surface that can push against the contact.

This is a remix of "Thomas the bottle cap" by @gaganchen [link to the original](https://www.thingiverse.com/thing:4969012).

I smoothed out the outside cylinder perimeter, elongated the body and added chimney which is also hollow, so the liquid can flow out of chimney as well as eyes and mouth openings!
