Bull Rider - 3D Printed Scooter

print and assembly instructions

Scooter overview

The Bull Rider was designed by 

Slicelab

 in collaboration with Stratasys. The kick scooter is comprised 

mostly of 3D printed parts designed specifically for the Origin One machine. The additional parts needed 
are off the shelf components that can be easily purchased online and customized to user needs. Examples 
of such adjustments can be for the users height or weight metrics that impact how one rides the scooter. 
Additionally, there are components like the long-board trucks, that can be tightened or loosened to allow for 
more or less responsiveness in steering. In the following pages, the required tool set and steps to complete 
this assembly will be highlighted along with a list of the needed purchased parts and printed parts.
