Spool Clamp

thingiverse

Create simple spool clamps for luthier projects using plywood and carriage bolts. These cost-effective alternatives to store-bought versions require a 1/4" carriage bolt, fender washer, wing nut, and disks made from 1/4" plywood with varying hole sizes. The OpenSCAD script and DXF files are provided for creating the required disk types. Assemble by inserting a square-end of the bolt into the square hole disk, followed by round hole disks, a cork, and finally securing with the washer and wing nut. Use several clamps for larger projects to save costs and enhance versatility.
