Hi
There's plenty on thingyverse..quick search will work
Main choices are
zip tie or clamp type
3 or 4 LM8 linear bearings
plenty with fan options
Personally i prefer the 4 bearing /clamp type but that means buying some M3 nuts and screws
I have no idea if its actually a lot better than the zip tie types just kinda "feels" better

Good luck
