I was not planning on using 80-20 because it would make it heavier than i want this design to be.
The angle aluminum that supports the axles is 3/16 inch thick.

Just a little lesson here.
1 x1 x 1/8" aluminum tubing weighs 0.5132 lbs per foot
1x1 80/20 weighs .5097lbs per foot
so in this case your design weights more than with 80/20 now this doesn't take into account the hardware weight. Also 1x1x 3/16" is not a common size for tubing typically it comes in 1/16 or 1/8"
