I had some craft knife blades lying around and I was missing a handle for a small amount of cutting I needed to do. So I designed this minimalist craft knife handle that allows for a decently good grip.
It’s probably necessary to print this with a few lines of brim (full raft not required), otherwise the tip will cause problems.
After inserting the blade, you can press the two parts together by hand or with pliers. They hold together quite well, but can also be seperated again quite easily.
New Version V2: The blade is much sturdier, but you may have to do a little more cleanup.
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.
