Mr. Coffee grinder converter

I have a Mr. Coffee Burr Mill Coffee grinder (https://a.co/d/6sThZyH) which comes with a container. I wanted the fancy grinder that you could hold the portafilter to fill it in. So I designed this converter and mounted it on the grinder. There is a screw on the top side of the grinder and I opened that screw and tightened this converter instead. It has two parts that print in-place. The sliding part still lets you turn off the bright blue LED by moving it out.

The portafilter that I use and I designed this converter for is from brim.

It is not perfect. Some coffee powders sometimes are spread around though but I have been using it for many years now and I prefer this way than using the container.
