Duplo Rail Mid with only 2 Colums

thingiverse

I utilized the nearly flawless geometry from pjotrx and revised the central section. Upon closer inspection, I discovered that the original middle section boasted three columns, which proved unnecessary as two columns achieved the same outcome. This modified design boasts a significant advantage: it reduces material usage by approximately 25 grams (initial weight: 104g / revised weight: 80g). I also addressed minor edge roughness on flat surfaces to enhance the overall finish. Additionally, I encountered an issue with my CAD tool's dimension accuracy, necessitating a tenfold scaling adjustment to achieve the correct size. Fortunately, this process can be effortlessly accomplished using Cura.
