Hit things in style with THWACK! A 3D-printed plastic hammer.

This lean, mean, ball-peen is ready for your general clobbering needs! And while it won't drive a galvanized nail into a pressure-treated fence-post, it will dutifully bludgeon interior nails, bang tight-fitting objects together, annoy individuals with experimental jazz percussion and acceptably intimidate others when held menacingly.


V2 - The peen has facets now to promote better printing at smaller scales and in general.

sudo THWACK - a request from Vik, this is useful for executing "bash" commands.

unix nerds of the world unit! Thanks for that. sudo indeed.

And done.  The "system" font that comes with windows isn't contoured for path-tracing in programs like Autodesk Inventor and Adobe Illustrator so I dove deep in to my 80,000 font collection to find a raster-inspired terminal font.  I hope it works for you!

Cool, I have a rubber "sudo" mallet but I feel the need for a test object to perfect my IMPLA recipe on and this looks just perfect!

Me no speaky IPT, but how hard is it to make a derivative with  "sudo" in lower case terminal font on it? If a pain, let me know and I'll do it with more brutal graphics tools :)

I like the way you think.

I can't think of a more appropriate tool to execute a "bash" command than a hammer.  And the divine authority of "sudo" only makes it more "impacting."I'll upload the file this weekend.

Nice, I love the idea. What software did you use to render the images? It looks very clean and professional.

ErikJDurwoodII on Nov 13, 2012 said:

Thanks!  I used Autodesk 3D Stuio MAX to render the images  with the V-Ray rendering engine.

I like the arrow at the top, telling the user that either end can be struck.  ... for those as "dumb as a hammer." ;-)

Make a cavity for a very large threaded bolt and you've got yourself a real hammer. You could even have the threaded end protrude from the "peen" side and grind it round.

ErikJDurwoodII on Nov 13, 2012 said:

That is a good idea!  For those who don't want to bother with bolts or grinding, maybe I'll also make one that accepts a coin or something as a striking surface...

Is this printable?

ErikJDurwoodII on Nov 13, 2012 said:

I'm printing one right now to check it out.  As long as your printer can ooze a bridge well enough, I don't see an issue.

I'll let you know!
