Doweling Jig

thingiverse

This is a basic jig for drilling 1/4" holes for wooden dowels when assembling woodworking projects. In addition to the print itself you need 3/8" OD / 1/4" ID oilite bushings which are 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 are there to let you attach a thin piece of acrylic with screws which 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 just be careful to let the drill bit/jig cool down between holes to reduce wear and tear.
