Duplo 2x4 block, 6 blocks high

thingiverse

Building bridges with Duplo tracks requires a substantial amount of blocks. For each story height, six blocks are necessary. However, when creating multiple bridges to reach a table or similar structure, many additional two-by-four blocks are required. As someone who values efficiency, I designed a high-density two-by-four block that stands at 6 blocks tall. Printing a single unit takes approximately 8 hours on the M200 printer, while producing eight consecutive blocks in one weekend can consume around 550 grams of filament.
