What Happens When 3D Printing Meets Small Scale RC Models
The dogbones of the Losi Micro-T RC models are quite small in size and although they are pretty durable you might still end up breaking them due to wear off… especially if you upgrade your Micro-T with a more powerful battery or a brushless combo. So we’ve made a 3D printable dogbone that you can print and try on your small scale Losi RC model, these were originally designed to be printed with PLA, but regular PLA is not strong enough (though it may work on stock Micro-T), but printing from ABS does provide a more durable solution that should handle some upgrades. Do note that printing the dogbones with ABS filament may still not be enough if your Micro-T is equipped with brushless motor. This was all an experiment to see how strong 3D printed dogbones would end up with the idea to possibly make them shorter for a modification to a Micro-T Desert Truck.
We recommend to print using a finer layer height, 0.1 mm should be just fine as the dogbones are quite small in size and it could be challenging to have them printed properly even at finer resolution. Also make sure that you use support material when printing these, experiment with the position of the dogbone to see which one will result in best quality print on your 3D printer. On the photo above you can see a dogbone printed from PLA (black) and one printed with ABS (white) with the ABS one not as detailed as the PLA result, but stronger and more durable.
