I created this quick release for the luggage carrier on an Engwe Engine X or Pro. May also work on other bikes, but not sure. Works great with the Engwe 17-35L rack bag or Engwe 17L bag. But should work with most bags and even crates.

I printed this in PLA and it seems strong enough. If it breaks I will redo it in PETG.

I used crazy glue (secondelijm) to glue everything together as in the composite image. That works for PLA, for PETG you need to use some other glue.

The securing strips can be mounted using M3 screws and a washer.

Then you can use the velcro of the bag to mount the bag to the quick release. Additionally or alternatively you could use the holes in the mount and screws the bag to it.
