I was thinking about how inconvenient it is to carry my U-Locks in a bag while biking, then I remembered that I have a 3D printer! This should work for any U-Locks with a 15.5 mm diameter on the “U” part of the lock. In order to properly orient the layer lines for maximum strength, this design is split in two parts. Assembly requires four 12 mm M3 screws, though there is some flexibility for slightly longer or shorter screws.
The author marked this model as their own original creation.
