How do I expect to break the glass of the “break in case of emergency” box if I don't provide you with one?
When I was a kid, my dad gave me a small hobby/gem hammer. I never forgot the design. I thought it would be a perfect fit.
To print: split the STL. The head will print great with a bit of organic support for the handle hole. The handle itself had no issues printing head-face down, but I used a 10mm brim just in case. There's a .1mm clearance between the handle and the head that results in just enough friction for a tight bit but not so much as it's a struggle to join the two pieces together.
Enjoy! And thank you for taking a look.
