I know typically the file of the week is something that is a bit more Cube friendly but the 3D printed Bike Chain belt is still one of my favorite prints ever. I have been rocking this belt for the last 90 days and even though its sintered nylon, its still extremely comfortable. Its also super durable too. I may or may not have ran over it with a car to test my theory that its tough. Spoiler alert. It survived unscathed (but dont try this at home. You might drive a car bigger than our Cube ). Either way, its a personal favorite and its definitely worth checking out.
