Shop Dividers V. 2

The small holes are already threaded for 8x32 screw. However, I suggest running a tap through the hole because not all printers have the same tolerances. You will need to cut down a 1/4" bold, or cut a 1/4" rod. the length of the rod has to be 35mm long. The other hardware needed is a 1/4x20x 3/4" bolt, wing nut and two 8x32x1/2" screws. Assemble as the picture shows. These dividers are capable of scribing a 12" diameter circle.
