I sent my twin sister an old set of Craftsman combination wrenches with 12-point box ends. Her toolbox situation leaves a lot to be desired when I use her tools, so I knew I needed something to be able to find the wrench I needed when I needed to use one when we work on projects when I go visit her. That is where these designs come in.

Fill percentage, layer height, and material are flexible. Metric set printed in Hatchbox black ABS as shown.

The wrench bushings are designed to be held together with a length of #10 threaded rod (24 or 32 threads per inch, builder's choice). The largest wrench bushing has a void for a #10 hex nut. There is another nut and washer installed on the outside which locks the largest wrench bushing to the threaded rod. The other bushings are free-floating on the threaded rod. The small wrench busing has a printed-in flange and the wrenches are held on at the small end with a wing nut and a washer.

Metric set is designed to hold 6-mm to 18-mm (12 wrench set, pictured)

Standard (SAE) set is designed to hold ¼-in, 5/16-in, 11/32-in, 3/8-in, 7/16-in , ½-in, 9/16-in, 5/8-in, and ¾-in (9 wrench set)
