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

An octopus settles into a rocky seabed, one eye fixed on you while its arms spill across the panel in slow, deliberate curls. Coral fans reach up from the corners, shells and pebbles gather at the bottom, and every sucker catches a shadow. Carve this one and people will lean in close just to run a thumb over the texture. This is a high-detail bas-relief STL built for clean machining. The depth runs deep through the body and arms, then steps back into the rough stone background, so you get real contrast and shadow once the dust clears. It is sculpted and ready for Aspire, VCarve Pro, Carveco, and ArtCAM, and it cuts well on any hobby or pro CNC router. For a clean result, rough it out with a 6mm end mill at a 40 percent stepover, then come back with a 3mm ball nose at 10 percent stepover to pull out the fine sucker rows, coral branches, and that watchful eye. Run it in hardwood for a wall piece, a coastal sign, a headboard panel, or a statement gift for anyone who loves the sea. The file is an instant digital download, so you can be cutting tonight. Commercial use is included, which means you are free to carve it, sell the finished pieces at shows or in your shop, or hand one off as a one-of-a-kind gift. Add it to your library and let the octopus do the talking.

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.
