Allows Keurig 2.0 machines to use any non-DRM type filter. Idea taken from the "Keurig 2.0 DRM Freedom Clip" with an additional mod to get it to work without having to cut and paste a Keurig 2.0 compatible lid. Requires a "neon yellow" sharpie for this to work properly.Printed in white PLA with the lowest quality setting on my printer, which I believe is around 300 microns. Temperature for my filament was 220c. Key to this working is you have to color the inside bottom with a neon yellow sharpie. I purchased a pack of 6 Sharpies (multi-color) at Staples for around $6.
