LeBois GT v3.0 Belt Tensioner
The LeBois GT v3.0 project is another take on the belt tensioner idea, using a motor-driven spool layout in a compact DIY package.
Projects like this are useful because they show how much the result depends on packaging and implementation, not only on the motor choice. Two belt tensioners can aim for the same cue and still feel very different once spool diameter, belt path, and controller tuning change.
What stands out
Section titled “What stands out”- motor-and-spool approach
- compact printed housing
- designed around seatbelt tensioning for sim racing cues
Why someone might study this one
Section titled “Why someone might study this one”This build is a good reference if you are comparing different ways to package a belt tensioner around a seat or rig without turning the whole project into a large fabrication job.
What to check before building
Section titled “What to check before building”- spool geometry and how evenly the harness loads through travel
- stiffness of the printed housing under repeated use
- motor mounting and belt alignment
- service access once the unit is installed on the rig
The video is useful for seeing the mechanism in context. Treat it as a project overview, then verify build details from the original creator before you copy the design.
