Ladder For anything

I built this for my brothers hamster since he likes to bite through things and made it where he can't get up to the top of his cage it should work with other things to beware though it is small you may have to upscale it. It is 28cm tall and 3.5cm wide Printed at 100% scale on 0.2  layer height with 15% infill with PLA+ should work with other filament
