I-Beam

thingiverse

To create a custom I-beam for my project, I designed a sketch using SketchUp as my second attempt with CAD software. The beam measures 150 mm in length, 10 mm in height, and 5 mm in width, while its holes have a diameter of 3.0 mm. For printing, I utilized PLA material with a raft to prevent warping. Initially, I attempted an H-shaped design that proved unsuitable for adding holes; thus, I opted for a modified layout requiring fillets at the flange and web intersection points to print without supports. Overall, the process was successful.
