Inexpensive Soft Metal Bending Tool

This project may not seem extremely exciting but it is very useful and satisfying to create other parts with once it is finished.  It IS exciting, get EXCITED!  If you are a true Maker, you are already teeming with excitement over the fact that you are reading another instructable and expanding your mind's quiver.

Recently, I needed 90 degree bends in aluminum stock to create brackets for a project I have going.  I grabbed $25, ran to Home Depot and after a few hours created my own metal bending tool.  Quick, dirty, simple and cheap.

E até onde se pode ir, em Impressão 3D?
Que tal, notícia do Blogue da Ponoko, uma Canoa?

3D printed boat made from recycled milk jugs

WOOF (Washington Open Object Fabricators) made what may be the first functional 3D printed boat (any objection?). It was made with a 3D printer hacked together from a 4′ x 8′ plasma cutter and a homemade extruder. The material is #2 HDPE obtained by shredding 250 one-gallon milk jugs.
They entered the boat into the Seafair Milk Carton Derby. Apparently, their entry caused considerable debate and confusion, because the boats in this race are generally made from unaltered milk jugs strapped to a frame. The irony is that this 3D printed boat was the only entry made entirely from milk jugs without connection or support material.
