a.k.a **Tiny Touch MK3**, a bit more background on why I design this will be available on my blog.
**Printed parts:**

- body: printed on its back, mirror it for _left_ motor. Use a more malleable filament like ABS is recommended, easier to cut threads.
- flag: printed on its back, mirror it for _left_ motor.
- nut: print it twice.
- thread: print it slow, 0.2mm layer height at most. I print mine with 0.16mm.
- mount: optional. I design it for this carrier. But any 18mm sensor mount will work.
**Non-printed parts:**

- Optical endstop ([Aliexpress](https://www.aliexpress.com/item/32436920427.html))
- Tiny linear servo ([Aliexpress](https://www.aliexpress.com/item/32972306205.html))
- Servo extension cables — 3pin each.
- 3pin JST-XH connectors — 2.54mm pitch
