This is a postage stamp holder I made on the Longmill. The same STL file can be used on a 3D printer. To cut the slot for the stamps I just use the jog mode to cut the top. Also I have a laser engraver to engrave “STAMPS” on the top. Here is the link to the file. I use a “1 1/2” X 1 1/2" cedar board to make up to 6 at a time. You will need an extra long 1/4" bit 2 1/2" in length overall. If you scroll down on the page you can see the setup. 3D Printable Postage Stamp Holder by Kent Harris
