Improved SMARS track with multiple rubber bands
thingiverse
I designed a modified track to improve the stability of my previous design. The original rubber band was prone to falling off when making sharp turns or rotating quickly, so I added multiple tiny rubber bands to address this issue. Due to space constraints, I only installed 8 rubber bands on each side, which proved to be sufficient for achieving optimal results. Installing the rubber bands from a sideways angle, as shown in the picture, made it easier to secure them properly. The additional tension provided by these rubber bands significantly enhanced the performance of my design, rendering it much more reliable than its predecessor.
