Basic little cap to fit over windbreak top to provide a place to hang a bag or what whatever you want.
Just went camping for the first time last week and was looking for things I could improve using a 3d printer.
One thing I did find is I was using plastic bags as a bin but had no where to hang them, I made this little cap to go on the top of my windbreak.
The hole is 29mm ID and I printed mine in glow in the dark ABS as it might look good when the sun goes down.
printed at 0.3 layer and 20% fill with raft to support the top.
