About this 3D model

The idea is simple, just print it out and glue a magnet inside the hole. I uploaded the f3d file (Fusion360) because there are several models of pencil like this. Besides that you don't need to use the same magnet size and shape as I did. 06/25/2021: Uploaded another model (ring type) Check what you have at home, measure everything, adjust the file and have fun! ===== If you'd like to support me you can post a make, comment and/or pay me a coffee at PayPal
