Duplo and Hubelino compatible marble run parts

thingiverse

There are already a couple of good models for LEGO Duplo compatible marble run parts that have been created, but most of them didn't work out for me so I designed my own from scratch. The marble cutout is identical to the one used in Hubelino parts, which means they can be combined seamlessly without any issues. I strongly advise using a brim on the bridge, especially when printing the smaller piece, as it has happened to me before that the small contact area caused it to lift off the print bed. If an additional model with an added brim is necessary, please don't hesitate to let me know. It's crucial to have a well-calibrated printer in order to connect the original Duplo pieces to these models successfully. I highly recommend printing the perimeters first to ensure precise dimensional accuracy. Some of the pieces might not fit perfectly, and I haven't printed all of them yet, so please don't hesitate to let me know if you encounter any problems. If there are some missing pieces that you need, just let me know and I'll do my best to create them with my limited modeling skills. I hope you have a great time using these models!
