About this 3D model
This is my version of a 5 inch holder. I have also added a version for “old/cheap” grinders (see pictures) As always as an engineer, I recognized a problem and wanted to solve it with extreme solutions. Of course, once again I wasn't satisfied with what was available so far or what I found... either it didn't fit well or something else. I then made the part from scratch. It fits perfectly for 5"/125mm sanders. All sharp edges are removed. You can now simply slide in from the top without getting caught on an edge or anything.
