Would PETG have worked better?

That would be awesome, thank you!

Completely agree with Mr. Moving over here. Whenever I encounter something like this, (even with my recent toilet paper holder) I will print sideways.

I’ve made a design with thicker pegs as well as adding modifiers to make the pegs to be solid instead of hollow. It should also be a similar drop in replacement to the one you had printed. You can try printing it out and see if it works out for you.
