Bicycle Chain Guard
thingiverse
This is a bicycle chain guard to help keep your chain from coming off the main sprocket when you go over rough terrain. This design clamps around the seat post tube and fits over the main sprocket. I saw something similar before but I designed this one from scratch to fit my sons' bike. I modelled it using Fusion 360 software and printed it on my Ender 3 pro. Works great.
