Ultra short road - VTech Marble Rush compatible

“Third-party product compatible with Marble Rush™. Marble Rush™ is a registered trademark owned by VTech Holdings Ltd., with no affiliation to this product.”

This part connects two building blocks placed side by side, to prevent the marble from slowing down due to the gap between the two elements.

Note on supports : supports are optimized to remove easily with minimal marks BUT you must be gentle and wait for the part to cool down. This is even more true if you decide to use more fragile filaments like PLA Silk or PLA Matte.

My son received a second Marble Rush circuit from VTech as a Christmas gift, and I found it interesting to be able to complete and improve it with 3D Printed models.

I found a set of .stl models online but :
- the models were difficult to fit into the original parts, which damaged them...
- the models were less flush than the originals once fitted
- the two 2x-upturn_road models had overly wide fixings making fitting impossible, and simply reducing the part made it too short...
- the plates were hollow and therefore required a lot of supports, so I closed them with low infill: faster to print and less filament waste in supports! (yes, the original brand ones are hollow, but only so they can be stacked. Here the 3D model was not stackable anyway...)
- the plates had a small useless recess that created a weakness, I removed it
- the shape of some parts requires a lot of supports, so I decided to work on optimizing them to offer print profiles on MakerWorld to make things easier for Bambu Lab owners in the same situation as me.
- the strength of some PLA 3D Printed parts was very poor, yet I find it to be the most suitable material here! So I worked on the orientation of the parts on the build plate as well as the infill.
- many elements are missing, I added them either by significantly modifying the models or by creating them entirely. I hope to add even more!

I therefore offer you various parts to create a Marble Run compatible with VTech Marble Rush circuits.
There are extra parts that are not in my original sets (I don't know if they exist in the brand) and which I find very practical: the part to join two blocks (Road_blocks_join), the one to close a block end (Stop_block), the element to build a tower without using useful blocks (Building_block_tower) and the 1x1 and 3x1 plates.

I am showing you photos of what I was able to 3D Print directly with the profiles I offer, but obviously the print quality (appearance, strength, ease of support removal) will greatly depend on the quality of your filament calibration! And the result will be much better if you use specific filament for the support interface (which I didn't do because this type of part has more of a mechanical role than an aesthetic one for me...)

I deliberately 3D Printed my parts in gray to differentiate them clearly from the original colored parts.

If you find better settings, please share them! I will test your print profiles with genuine interest!

Work done from models https://www.printables.com/model/839010-vtech-marble-rush/files which were very generously put under CC0 license.
Note : My models are not under CC0 License because I spent a lot of time working on both modifications and support optimization, and some elements are personal models. I would also like to continue to follow their evolution (remix) which the CC0 License does not allow... Feel free to take the original models if you wish to modify, share, or sell your results!
