This is a 120 degree V-groove cutter for foamcore board (foam board, foam core). Design is included in Fusion 360, for you to remix with the tolerance you require.
Using this 120 degree V-groove cutting tool, you can make triangular shapes out of foamcore. As a triangle is the strongest shape, it is useful for making strong tubes such as for a handle for a sign.
To enable one to better express one’s self, and to prevent arm strain in the process, it’s useful to hold your message up high with a stick. In some cities, such as NYC, demonstrators are prohibited from using wooden sticks to hold up signs. Using this cutter, you can make relatively strong (and safe) triangular tubes using foamcore to serve as a suitable sign holder. Starting with a 20×30 inch sheet of foamcore, you can make a handle and still have enough real estate to share your message.
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.
