3D printing scooter zipper

Posted on September 16, 2021 by William

It’s fun to play with tools around the city center in a private electric car, but it’s even better if you like it [James Dietz] Then ride Your own 3D printed electric scooter. As one of the entries for the Hackaday Award, the goal of RepRaTS (Reproducible Rapid Prototyping Transport System) is to do the original RepRap project for scooters for 3D printing: to provide a user-friendly design basis that you can make Expand, modify and maintain. It doesn’t even need power tools to build, except for your 3D printer, of course.

The design uses threaded rods and special plastic gaskets to withstand large loads. The prototype deliberately uses a large in-wheel motor oversized, but most of the build may be smaller. As you can see in the video below, the scooter seems to be driving very fast and has good handling.

[James] WARNING The scooter is not yet safe to use. There are many battery installation and safety issues that need to be fixed. We look forward to seeing the final version.

The 3D printed parts are all PETG, the nozzle diameter is 0.8 mm, and the layer height is 0.4 mm. The filler is a fairly modest 30% grid and does not require support. Tightening the threaded rod is critical, and there are specific instructions on the tightening and bonding steps required.
