I love using magnets in my 3D printing designs, It’s a great way to make a lid lock into place or to easily make tool holders. I normally use rare earth magnets or neodymium magnets, But while I was looking I found you could buy a strip of the more weaker black flexible magnets in meter long strips for as low as £1.40. I ordered a strip to see if I could use this to make fridge magnets, Turns out it’s great for this and it’s got a adhesive backing to it.
In my designs I added a cutout of 14mm x 2mm x whatever length the design is. You don’t have to have the magnet run the whole length of the design. I kind of found it out by accident but you don’t even need support when printing on my ender 3 pro.
These are designed using Freecad and they have provided the files so you can edit them how every you want.
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.
