TPU Hammer Mallet Cap Generator

Convert your steel hammer into a non-marring mallet with this parametric TPU hammer cap! Perfect for tapping wood or 3D printed parts into place without damage.

This design revisits one of my earliest models with improvements to fit, and style, but the biggest upgrade is it's now parametric! Simply measure your hammer's face diameter and distance to neck, then hit the “Customize” button to set these values for a perfect fit.
