I designed this hook to hang bags on our Mountain Buggy Duet stroller. This is a version with gyroscopic cupholder. To assemble it you need 4 M2.5 screws with nuts and to secure them I use Loctite glue. Hook_with_holder should be printed upside down with supports.
You don't need any tools to mount it to the stroller, it just snaps on the centre pole so it is easily removable.
Also check out my hook without cupholder.
Update 01.05.2023: as this model is designed for a specific stroller (Mountain Buggy Duet) I added the *.step file to make it easier to remix.
The author marked this model as their own original creation.
