Similar to a commercial pull bar. The end that gets thwacked is purposefully overly thick, as this was a failure point in previous versions (these are usually made of steel).
I printed with 3 wall loops and PETG.
Print on it's side and you won't need supports. Brim is recommended.
V2 model added, which removes some thickness from the tall end in favour of a more gradual ramp transition to add further strength.
The author marked this model as their own original creation.
