This is a collection of basic elements for 1515 extrusion work.

I have an excess amount of M3x8 screws so my brackets are configured to use them unless there's a good reason to use something else.

• standoff - motherboard or other board (pci raiser) standoff. The feet hold the nut in place so that you don't have to align three holes at once... This is one example where M3x10 or even M3x12 is more appropriate!

• support - off-extrusion motherboard support. Useful when extrusion is not aligned exactly with the holes that need it.

• l-bracket-1x1 - can be used for medium-duty loads like motherboard, etc

• l-bracket-2x2 - I use these at the corners of enclosures

• foot - special version of l-bracket-2x2 with recesses for screw heads. Give some love to your table :)
