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.

About this design

A speckled brown trout stretched across a bed of riverbank grass, a worn cork rod handle and a classic fly reel resting beside it. This is the kind of scene that stops an angler mid-stride. Carve it and you get that quiet morning-on-the-water feeling baked right into the wood. Under the hood it's a high-detail bas-relief STL with real depth and honest texture. Every scale, the layered spots running down the flank, the fin rays, the knurled reel and tapered rod, all of it reads cleanly once the toolpaths run. The file is built for Aspire, VCarve Pro, Carveco, and ArtCAM, and it carves beautifully on a CNC router or comes through crisp on a 3D printer. For the best surface, rough it out with a 6mm end mill at 40 percent stepover, then come back with a 3mm ball nose finishing at 10 percent stepover to pull out the fine scale work and the grass blades. Walnut, maple, or cherry all suit the natural outdoor look. Use it for cabin wall art, lodge plaques, man cave signs, lake house decor, or one-off gifts that any fly fisherman will actually keep. This is an instant digital download, so you can have it on the machine tonight. Commercial use is included, which means you're free to carve these, stock your booth, and sell every piece you make. Grab the file, dial in your stock, and give the trout fishermen in your life something built to last.

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.
