I needed a general purpose handle to add to my 3D printer station to allow me to move the board about. I searched and found one set of handles but they were quite plain, so I created these, designed to fit most hands comfortably, including a thumb rest.

I've since printed another set for a washing basket table I made for putting out the washing on the line! Works great.

I use M6x80 screws both times: the head is really too large for the slot but I've used extra epoxy resin to cover it over. An M5 or smaller head would be better!
