Kohlburg Bike Chain Lock Case

thingiverse

I have created this case in order to protect my bike from the lock of my Kohlburg chain lock. Withouth it it would constantly hit against my bike and scratch it. This case works fine without any clips or so and only is held in place due to friction. I have added several versions with different internal clearances between the case and the lock (0.15mm, 0.2mm, 0.25mm and 0.3mm). For me 0.25mm works quite well (maybe a little bit too loose but still tight enough that it will not fall off on its own).
