Duplo and Hubelino compatible marble run parts

prusaprinters

<p>There are already a couple of good models for LEGO duplo compatible marble run parts. Most of them didn't work for me so I designed my own. The marble cut out is the same as for the Hubelino parts (commercial marble run parts) so they can be used together without any problem.</p> <p>I recommend a brim for the bridge, especially for the small part. It has been kicked off the print bed for me once due to the small contact area. If an additional model with an added brim is necessary, please let me know.</p> <p>It is important to have a well tuned printer to be able to connect the original duplo pieces with these models. It is recommended to print the perimeters first to have a good dimensional accuracy.</p> <p>Maybe some of the pieces to not fit perfect. I did not print all of them for far. Let me know if there are any problems.</p> <p>And if there are some pieces missing for you just let me know and I can try to make them with my limited modelling skills.</p> <p>Have fun with these!</p> <h3>Print instructions</h3><h3>Category: Construction Toys Summary</h3> <p>There are already a couple of good models for LEGO duplo compatible marble run parts.
