I wanted to try adding magnets in my 3d prints, and I wanted to try making a diffuser for my amaran al-mx, I made this diffuser, it uses 4 magnets with a diameter of 6mm that are 2mm high

be careful when inserting the magnets and printing over them !! I added .2mm tolerances, but I'm not responsible if you don't insert magnets properly resulting in your nozzle hitting magnets damaging your printer ! ( I'd advice to slow the printer down a lot to print the layer that'll cover the magnets )
