I designed this thing to open “brush-in-can” plumbing adhesive containers. These adhesive containers use a standardized 45mm diameter knurled lid. The lids usually become impossible to remove with bare hands after the threads get jammed with glue (often after the first use in my case). So I keep one of these tools handy in the box where I store my plumbing sundries; it easily beats having to reach for the slip jaw pliers.
No supports are needed. I printed my tool in ABS, 0.4mm nozzle, .45mm line width, 25% infill, with 4 line walls. The result feels good in my hands; ie it is very tough/durable, yet easy to squeeze tight for a solid grip. Other filaments will work, but semi-flexible filaments like ABS or nylon will make a tool that is easier to squeeze, versus stiffer stuff like PLA.
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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
