Trench support
thingiverse
you will need to print the main trench support x2 for both sides. the side supports fit in each other so 4 per side. pins I used are just M2 screws. this is designed to go into a hole dug out so it does not collapse on the workers. for scale toys like Bruder. If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design. Thanks, Enjoy!
