Tropical Singing Fish (animatronic) fixing parts

The small tropical signing fish I had after opening had a bad part, that was too loose around the square metal pole, and didnt turn anymore.

So I created this, alongside screw poles (which you can just glue on a flattend/sanded surface, mine all were broken, so I kinda had to replace them).
The mechanical part has a little bit of an inset to place and glue the screw inset, so it is easily printable. (use strong glue, or widen the screw hole up front)

Picture one you can see the original part next to the (two part) printed part. (and the screw poles/standoffs on the side)
