I-Beam Construction

This is an example of I-Beam Construction. The OpenSCad files are enclosed incase you want to modify or improve on my design.

By the way, I did a small test tonight and my I-beam was easily able to hold up my backpack that weighed 6,415 grams which is 377 times heavier then the 17 gram I-beam. I think it could have easily held more.
