The canopy mount on the stroller broke and getting spare parts was difficult. A copy of the original design is attached, but it is weak and difficult to print. I therefore made a stronger (thicker) version that is split in two parts for easier printing.
Technical
About 17 grams of plastic is needed.
I recommend to print the strong version which is also split in two parts for easier printing. Rotate the bottom part so the flat side is down and use supports of the spring on the top part.
I printed it in ABS but PLA should also work.
Glue the parts together using Loctite repair extreme, super 60 or similar.
