BEGODE A2 - rear bumper/rest

I needed a taller bumper for the A2, so I designed one.
It fits the stock bumper mount and it also fits this trolley handle https://www.aliexpress.com/item/1005005871999876.html

Print it in TPU or another flexible material (is there any other?)
6-8 walls, 25% infill

Hope it helps someone :)
