Seatbelt Buckle Extender

My seatbelt buckles in the back of the car recess into the seat which was a significant pain point for my son trying to buckle in. This is a simple clip that fits around / under the seatbelt buckle stoping it from recessing into the seat when he tries to push his seatbelt in.

I have set designed it accordingly so that when printed the layer lines wont force a weak point and break.

I have also included the Fusion 360 file if you want to edit it for your own car.
