Chicco toddler High Seat buckle part

My baby high seat buckle has been lost... so I had to find a solution.

This is a Chicco high seat buckle where both sides right and left join into the middle part that goes between the legs.

For this model, starting from a Decathlon model available on Thingiverse, I adapted it smoothly to have a middle separator with different width and length.

As we are.. version 4 : my wife said "it's good enough" so I reached my goal :-)

Feedback welcome !
