I finished mine tonight. It was inspired by the Moon Tiles project on the Bantam Tools site. I made mine a lot smaller though so it would be easier to find a spot to hang it.
Using the Far side of the moon topography stl from NASA. I put the stl in Blender and used the decimate function to reduce the mesh. Then I used Vcarve desktop to import the file and select a section that I wanted to use. I used a 46286 1/8 tapered ball nose from Amana with a 3d finishing path. Took around 1.5hrs to cut.
I couldn’t figure a way to cut the design in to 4 squares. So I just cut the wood up before milling it.
I also got to finally try aluminum. It worked well but near the end I broke my bit and didn’t have any more. So I only have two side brackets.
Overall I am really pleased with how it came out. I did have issues at first. When the endmill would change directions it left an indent in the piece as seen below. This left an X shaped line in the whole piece. I think it was because my settings for the bit were no good, I was using some Chinese amazon ballnose that I got with my used machine. I ordered a set of Amana ones and used their settings in vcarve and it remedied that issue.
I also put my Carbide Create file for the brackets on Cutrocket.
