Bass Pedal Beater Head - Hammer Style

Didn't like the felt heads on my double bass pedal. Made these based on what I saw some other heavy hitting drummers using & put them on. Immediately noticed they had better reaction, less effort to strike the head & louder strikes. Print with supports, flat side down in TPU. I used 4 walls & 30% infill, they felt comparable in stiffness to the felt heads I removed.
