Crosscut Sled Runner Set for DeWalt DWE7491

These 3D-printable miter runners are precision-designed for the DeWalt DWE7491 (and DWE7491RS) table saw miter slots. The design uses dovetail-locking segments to reach a length of 390mm, ensuring smooth, consistent travel for your crosscut sled base. I recommend a length of 15.5" (394 mm) for your sled to match these runners.

Note on Compatibility: These are explicitly sized for the DWE7491 miter slots. The runners are 19.36 mm wide. I included a small segment to use for a quick test print to verify the fit on your specific machine before committing to the full print.

- Need a different size? If you have a different table saw model, leave a comment or message me with your miter slot width—I would be happy to adjust the model for you! Bambu A1 Mini Users: Please use the included print profile to print one runner at a time.

Usage Instructions

- Place the runners in your saw's miter tracks using washers or coins as spacers to lift them slightly above the table surface. - Apply a small amount of two-part epoxy across the top surface of the runners and carefully place your plywood sled base on top. Avoid too much glue that will leak onto your table saw. - Place a bit of weight on the plywood and leave it for at least 30 minutes for the epoxy to set. - Once the glue is dry, drive short #6 or #8 wood screws through the screw holes in the runner to secure the runners to your sled base. Safety First: If you're new to woodworking, make sure to check out a few YouTube tutorials on crosscut sled construction before you begin!

For best results, print on the textured PEI plate, as the texture provides a superior grip for the epoxy. PLA works but I recommend PETG or PLA+ for added strength and heat resistance. 3D printing the runners has the advantage over wood as it won't bend or warp from humidity changes.
