I needed an “L” (I’m not sure what else to call it) to close a 2 cm gap in my cabinet, so I created a simple design using Tinkercad. The measurements are: 200 mm in length, 69 mm in width, and 30 mm in height. The slim part is 1,500 mm tall.
Since the piece will be hidden, I wanted to minimise material usage. For that reason, I also created a cost‑saving version with a central hole. At the same PLA settings, the perforated design consumes 42,92g of filament instead of 50,57g.
