Doweling Jig

thingiverse

This is a basic jig for drilling 1/4 inch holes for wooden dowels when assembling woodworking projects. In addition to the print itself, three-eighths OD one-quarter ID oilite bushings are needed which press-fit into the holes in the jig. The bushings prevent wear and tear on the jig and help keep the drill straight. Also, the two small holes on the side allow you to attach a thin piece of acrylic with screws that can help with alignment and holding the jig to the workpiece with a spring clamp or similar. I'd recommend printing this with something like PETG or ABS because the drill bit can get hot enough to soften PLA. If you do print with PLA, be careful to let the drill bit/jig cool down between holes to reduce wear and tear.
