Small vee block

thingiverse

This is a small vee block for clamping or holding small objects, especially round stock or pipes. It's obviously not a high-precision block, but it is handy for jobs like hacksawing, drilling, and assembling parts. It measures 45 x 45 x 20 mm, with a 10 x 30 mm rounded slot that is 10 mm from one side and 25 mm from the other. There are two holes for M4 nuts and bolts, and the included clamping arm can clamp round stock as small as 10 mm OD. The block can be inverted if you want a flat surface and not the vee.
