Roller Blinds tube support

I have no idea of which brand this is or what the correct name is, but it might help someone on a pinch. Its the part where the tube goes thru and it has a small hole so the cable can coil nicely.

I'm also adding the stopper used to clip the cable.

Print with supports like in the picture attached, this way the weakpoints wont be where the stress is applied (I think).
