It was still sealed (apparently) and everything supposed to be in it, it was.
But of course ... it was .. it is, broken.
Let see if it can be fixed. If not ... well, is a very good source of interesting components !
The electric curtain is a series M1 of GranDekor brand and the problem is related to one of the curtain holder (the gearbox) not be able to stay connected to the motor.
Btw, the model I found has of course the remote and a rechargeable battery pack embedded in the motor housing.
Very very neat.
I did proceed to test the motor and everything is working nicely, only a couple of things are broken.
The cover for the motor block, that ends with some hooks to connect the gear box controlling the curtain, and another plastic piece on the motor itself that has a hook missing.
Since I do have a 3D printer I though "why don't try to design and print the broken parts ?"
The broken pieces
As mentioned there are two broken pieces.
- the main cover of the motor box
- a cover on the motor
The motor box cover

Not sure if PLA will be strong enough, it should be.
Anyway I plan to print the pieces in PLA+, little bit more sturdy.
The cover on the motor seems made in teflon, that can be a problem, but anyway the first challenge is to design the pieces.
The motor box cover
It seems the most easy piece to design but is not.
Is about 20.6 cm long and that already means I will have to orient it on the diagonal or vertical since the is on the limit of printer plane.
Plus the position will affect the strength of the piece.
Ideally should be printed upside down to avoid to use support, but it has the two hooks on the top, thus printing it upside down would be mean to have support along ALL the print.
So I will have to design and print it on the other side, with still the need of some support (and thus a painful cleaning process after the print).
Plus the inside of the cover will need to have some structure, is not just a plain empty inside.
I'll start to use TinkerCad because I already used it in the past, is free, I don't have time to learn other tools.
