Estimates for a mid-size hobby machine (Shapeoko, X-Carve, Onefinity class). Scaling all three axes together keeps the depth in proportion; for thinner stock scale Z on its own. Hardwoods with fine grain (cherry, hard maple, walnut, basswood) hold this detail best. Check your exact setup in Will it cut, free, nothing uploaded.
How we estimate carve time
Finishing is one raster pass over the whole carving with the ball nose shown, at 10% stepover and half of a 1,800 mm/min (71 in/min) feed. Roughing assumes about 45% of the block above the base is waste, cleared with the end mill shown at 40% stepover and 3 mm per pass (1.5 mm for the 1/8 in end mill) at the full feed. The model leaves out acceleration, tool changes and moves between passes, so a real job usually takes somewhat longer. Times are rounded to 5 minutes.

Opens directly in Aspire, VCarve Pro, Carveco, ArtCAM and Fusion 360, and in any slicer for 3D printing. For a laser, the relief is first turned into a greyscale depth image, which our Laser Studio app does from this STL. STL only, no OBJ or DXF: the DXF files used in CNC work hold 2D outlines, not the 3D relief surface. Scale it to whatever panel you are cutting. Scaling all three axes together keeps the depth in proportion; scale Z on its own for a shallower carve. How to open it in your software.
"Love these, and seller is very good with help! Would definitely recommend! And they are awesome with the customized files."
"Fantastic file! The detail is incredible, the toolpaths were clean, and it carved beautifully on my CNC with very little cleanup. The finished piece came out exactly as expected.…"
About this design
Have a laser too?
Burn this design, or burn onto it
Laser Studio opens this STL with zero conversion and turns them into a ready-to-burn 3D-illusion engrave. Carving on your CNC instead? CNC Match lines up a name, a date or shading on a photo of the finished piece, so the laser burns right onto the carving.
