Minimalist Duplo - Brio, IKEA, Wooden Train adapter that you can use for connecting Duplo bricks with wooden train tracks to make bridges and slopes. The peg on the outside is modified a bit so it fits on a Duplo brick too.

Print with PETG, 20% infill, no supports needed.

UPDATE 2025.01.11. I added male-male version with stl and f3d source files.

Update 2022.02.13. I updated the model (v8) with a more stylish peg, which is only cut in the bottom part to fit with Duplo studs. Thanks @Detri
