I created a model to help securing mount the brake sensors that come with the E-bike conversion kits to a Shimano brake lever. There were a couple of others, but they were not specific to mine or the designs required glue etc. This one uses screws and a zip tie to hold it together.

I saw another post of someone using a shoe rack to store their filament spools. That setup had a number of disadvantages so I modeled a new bracket to hold the same bars that ship with the shoe rack. This system has numerous advantages over the original kit and even over the original kit with the 3D printed spacers that others have designed.
