Double Plate 3280 $0.69
Drop in 3376 $1.70

What supplier was this order for? Also, is what you term a "butterfly" just a corner or L bracket?

Most 80/20 hardware, as far as I'm aware, has 1/4-20 threading; make sure to have a variety of lengths below 1" for mounting. Depending on the application, you'll want either a corner or L bracket (both of which are compatible with extrusion).

Having some 1/4-20 taps on hand may prove useful as well; we occasionally find threading the center tube to be useful when mounting pieces.

You may want to buy some other materials, such as wood or lexan - cardboard even - for prototyping; there's only so much you can do with 80/20, and it's sort of overkill for a proof of concept imo.

Butterfly he means end fastener those are 8020 parts

Bar 1 has the butterfly screwed into the hole running down the center by tapping the hole

Bar 1 is attached to bar 2 by sliding the butterfly in like a tnut and tightening it down through a hole in the bar called an access hole
