Hey,this is just a little caddy for any stuff like grease.I loaded up the original files so that you can print any letter or name or pictogram. You should have a look how thick your first layer is going to be and adjust the height of your letter to it in order to obtain that rough surface.Then just print with top/bottom plane facing to the build plate without any support.I think the screw-cap should work well without any finishing process but fasten and undo the cap several times til it slides smoothly.Unfortunately I actually can't send you any pics because all five I've printed are given away :-)
