Parametric Caster Stop - TPU

I use these to stop my office chair from rolling whilst pushing pedals on my racing sim setup.

Open Fusion 360 parameters and look at the User Parameters only. (see image)

• measure your caster wheel accurately 
• change WheelDiameter and WheelWidth 
• you may chose to change other parameters (optional)
  • Use Draft to change the outer angles 
  • Use Rim to change the thickness of the shell 
  • Use Buffer to add length in the ‘rolling’ axis

*you could scale the .3mf in your slicer and get it close, if you don't want to fiddle with parameters
