My 5y/o wanted a hook for his Haloween costume. I wanted something durable that was comfortable enough for him to hold for a while (I don’t want to get stuck carrying it). I designed this with the hook getting thicker as it goes for strength and a hex-shaped grip for comfort. He’s been walking around with it constantly for 2 weeks, picking things up, swinging off things… and it’s no worse for wear.
I went through 3 versions of the cup, all are published if people want different sizes. The small one was comfortable for him but didn’t completely cover his hand. The large one didn’t look realistic and is big enough for a small adult hand. The middle one is only slightly bigger around than the small one but much deeper, it hides his hand completely and almost looks plausible as covering a stump.
The cup sizes (length of the grip inside/ID of the cup): 70mm, 75mm, 85mm
The hook looks good on all of them and they all use the same socket for it so it’s interchangeable. It would even look good on a full-size adult (if someone is interested I can design a bigger cup for one).
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
