This listing is for DXF cut files to make your own 1 x 2 x 3 inch fixture blocks for welders and fabricators.

These 123 block files are designed to be cut from 0.25" thick steel.

The parts are self-aligning or self jigging (the parts locate themselves), simply clamp them together and weld. 

Slot and tab interfaces have a 0.005" clearance for accurate alignment.

Designed to be a simple welding project that can be useful for a lifetime.

Included model versions: 

• One version with a centered 0.625 clearance hole (0.628").
• One version with no holes for maximum squareness (holes can distort the material). 

This listing is for digital files only; no physical product is being sold here.
