As it's a Gunpla I want to build before I die, I'm currently building a 1/100 Dendrobium from scratch.
I finished the Mega Beam Cannon today, and together with the I-Field Generator I built previously, this means two parts are complete.
The materials used are 80% plastic sheet, 15% putty, and the remaining 5% 3D printed.
Although I'm a digital modeler, I'm choosing to build this using analog techniques, scratch-built plastic sheet.
There are so many skills you can gain by making things by hand, so I'm devoting myself to working with plastic sheet metal, thinking of it as an investment in future model making.
