This is a tool less replacement adapter of the SSD caddy of the Atomos Ninja V.
No screws or tools are needed in order to use your SSD with your Atomos.
Also included is the clip (you have to print two of them) for the Smallrig 2209 cage for the Ninja, as the original ones cannot be used with this adapter.
I believe it's better to print it in PETG for better heat resistance.
I have used supports, but YMMV and you may not need them.
The author marked this model as their own original creation.
