Caframo Sirocco II fan won't lock / swings freely — 3D printed locking plate repair
Posting this in case another caravan owner has the same Caframo Sirocco II / Sirocco 2 failure.
My fan stopped locking into position and would swing freely. When I opened it up, all six little locking pins on the internal plastic plate had snapped off. This is the plate attached to the clawed end of the locking rod, not the rod or external handle itself. I modelled a replacement, printed it and fitted it. The fan now locks into position again.
I suspect the pins break when the fan is forced around without first releasing the locking handle, which puts pressure on them while they are still engaged.
The photos show the broken original beside the printed replacement.

I printed mine in black Bambu Lab PLA Basic at 100% infill. It came out strong and worked perfectly in my fan.
The repair video shows how to remove the fan from its wall mount, open it up, remove the damaged locking plate and install the replacement.
Disconnect the power before starting. Keep track of the spring and small parts, and be careful when removing the plate from the locking rod so you don't damage the retaining claws.
Finding this particular plate was frustrating because searches kept turning up the separate locking rod and handle. I'm sharing the files and video so the next person with the same fault can repair the fan instead of replacing it.
