Simple tool to keep your alabama rig/umbrella rig from snagging on stuff and rattling around, just slide your line through the slit and pull it over your rig.
Just got into 3D Printing and this was at the request of a friend so it is also my first model, I've included the STEP file in case someone with actual skill would like to improve upon it :D
Make sure your seam is set to the back of the model so it does not affect the gap of the slit.
The author marked this model as their own original creation.
