These Stick Savers are meant to be attached to the thumbsticks of an Xbox controller to prevent movement (and hopefully any potential damage) while transporting the controller in a bag.
These are a remix of the Joystick Savers by Skylancer on Thingiverse. I ended up remodelling them from scratch mainly to smooth out the "wings", but also to build the hex filler pattern into the model so I didn't have to use a specific slicer or mess with removing top/bottom layers and adjusting the filler in the slicer.
I've taken my controller with me on a couple trips and so fare these have done a great job of preventing the thumbsticks from moving at all, so I can only assume they're also preventing potential damage as well.
Print with a 0.20mm layer height and 100% infill. No supports or brims needed.
After printing, they can be a little stiff to begin with, so I just used them like fidget toys and connected/disconnected them a hundred times while I worked until they loosened up.
The author remixed this model.
