Anti-bounce Ball Hammer

thingiverse

This is a remix of the Hammer by Walter. It use some 5mm metal balls to insert into the head. Using this balls offers 2 advantages : -It add weight to the head -and the "flying" balls absorb the impact Those 2 points add more inertia to the hammer making it more efficient. I also add parts which i called "shoes" for 2 reasons: -It is easy to change the day it will be damaged, and it use less filament -you can use different filament for different uses. I personnaly printed one shoe in PLA to use it as a hammer, and one in PETG to use it as a part remover. It could be interesting to test other filament like flexible and PC. The Head and the Handle stl have a tolerance of 0.2mm. I exported the shoe with different tolerance to be able to fit with any printer tolerance and/or different filament. Let me know if you need other sizes of gap for the shoe. Print Settings Notes: The head and the handle doesn't need a high infill. 30% is good enough. The shoe will need a higher infill, I'ld recommend at least 70% for durability. Post-Printing -Plug the handle into the head -Fill the head with balls through the head's hole. It doesn't need to be entirely filled, actually it is better to let free space to allow balls to absorb the impact. -Add one or two shoes. How I Designed This I was using the original one from Walter, printed in PLA, and I really like it. I was using it for many things. But after several mounthes it starts to crack (not really a surprise as it was in PLA). So I was thinking to reprint the head, then I got the idea of design martyr parts. Doing this I heard about hammers with balls inside....I went for it too. I wanted to be as close to the Walter's design. The head of my first prototype was closely looking the same. But I couldn't print it without having to deal with messy hoverhangs or supports, and it was creating issues to fit the shoes. That's why I came to a low-poly looking design. Designed with Openscad.
