Ninebot ES1 ES2 Doble Hook

thingiverse

I was fed up with getting my back soaked in sweat from carrying my backpack during the scorching summer months. To solve this problem, I installed a bottom hook on my backpack that enables me to secure it with a rubber band. This simple solution allows me to carry my pack without worrying about it flying out of the hook when jumping down curbs or navigating over bumps. If you're looking for an even more convenient solution, consider investing in a backpack equipped with a skateboard holder – this feature lets you attach your pack to a pole and keep everything secure.
