Introduction: 3D Printed Gadgets for Woodworking

About: If its practical, I have no use for it!

This is a collection of simple 3D printed gadgets for my woodworking workshop. All where designed in Autodesk Fusion 360, and I have included the stl files so you can print your own. The designs are pretty simple, so it should not be difficult for you to modify any of the parts.

Step 1: Clamping Brackets for Mitered Corners

The brackets are used to clamp mitered joints like picture frames and boxes. The miter angle does not need to be 45 degrees. When 3D printing use 50% or more infill for strength. Glue 80 or 100 grit sandpaper to the flat inside surface to prevent the bracket from slipping during use. The pictures show how the clamp brackets are used.

Step 2: Knobs

Make threaded knobs and handles for fixtures and jigs. The interior threads are 1/4-20 and 5/16-18. Thread in a hex bolt and super-glue in place.

Step 3: Rounded Corner Layout Templates

These templates allow you to mark rounded corners for 1/2", 3/4", 1", and 1.5" corner radii. Hook the template over the corner and mark with a sharp pencil. Then saw and sand to the line.

Step 4: Mortise Layout Templates

These templates are useful for laying out mortises on your stock for routing, chiseling, or a mortising machine. Draw the centerline of the mortise across the stock, line up the template, and mark it with pencil or marking knife. Templates are included for 1/4", 3/8", and 1/2" mortises for 3/4" stock.

Step 5: Temporary Corner Brackets

They provide extra 'hands' during the assembly of your workpieces. Useful for alignment during glueing, clamping, assembly with screws, etc. Use on corners or for T-joints. Sized for 3/4" stock.

Step 6: Angle Gauge

Set your saw blade to exact tilt or miter angles. 30, 60, 90 degrees. Design your own for other angles.

Step 7: Height or Cutting Depth Gauge

Easily set the height (cutting depth) of your table saw blade or dado blade for creating grooves, rabbets, or dados. The gauge includes 1/16", 1/8", 3/16", and 1/4" settings. 3D print standing on edge - no supports needed.

Step 8: Miter Slot Bars

These fit into miter slots on you table saw, band saw, router table, or sander. Use as stop, or attach to jig/fence/sled. Modify to fit your saw/sander/router table.

Step 9: Band Saw Insert

Replace a worn band saw insert. The file is for my Grizzly G0555 bandsaw. You may have to tweak the dimension to fit your bandsaw. Omit the center slot to make it a zero-clearance insert.

Step 10: Magswitch Jigs

Make your own Magswitch jigs. Shown is a featherboard using the commercially available Magswitch magnets (MAGJIG 95). You can design other jigs and reuse the same Magswitch magnets as needed.

Step 11: Dust Collector Adaptors

Make your own adaptors and fittings for dust collection systems and shop vacuums. The second picture shows a belt sander to shop vac adaptor. Use blue painters tape when you don't get the fit quite right! The dimensions are very specific to your machinery, so you'll have to design your own. I use a 2.4 mm wall thickness, 0.2mm layer height, 3 top/bottom layers, 3 outside/perimeter shells, and 35% infill where needed.

Step 12: Center Marker

Use this simple gadget with 8d nails to mark the centerline of a board.
