Calibration Hammer a.k.a. Hammer 2.0

I think the world is finally ready for my Calibration Hammer, a.k.a. Hammer 2.0!

The Handle Top part needs some supports (organic/tree supports are great for this!) but others print fine without. You'll need a spring between 4-5mm diameter for the handle and 1 M4x24 (or longer), 1 M3x20 (or longer), 1 M3x10 and 1 M3x8 plus nuts for them.

If you print the hammer head in TPU with high infill, it's perfect for bonking printed parts in their place (or out of their place on the bed).
