If you also have this type of blind and encounter the problem that the slats can no longer be adjusted, then this part is just right for a quick repair.

In most cases, it is only the gear in the adjuster that is over-tightened.

It is only a small part, but it has a big effect.

You don't have to throw away your otherwise fully functional blind.

Simply use a small pin to drive out the bolts that hold the adjuster housing together, insert the printed part, and close the housing again (with screws or simply with superglue), and the slats can be adjusted again.
