Jeti Transmitter Holder DS-12

This is a printed alternative to the item available at:

I decided that the price of the original solution was too high, so I decided to design my own solution.

For assembly you need:
- Folding brackets

- 4x KVT 345M4 threaded insert (but modify the .step model for any solution of your own)
- 4x M4x10 conical screw (for attaching the arms)
- 4x conical screw M4x12 or longer (for screwing printed elements to the device housing)
- 4x M4 self-locking nut (or regular nut + spring washer as in my case).
