Basically you can spawn a ladder. It uses the bomb attributes so the bottom will explode, although it is made out of an indestructible material so it wont break and you can move it around. If you place it on the ground it faces upward, if you place it on a wall it faces to the side. I tried to make it as easy as possible to stack them too.
 
How to install in case you don't know:
1. Go to This PC/Program Files (x86)/Steam/steamapps/common/Teardown/data/vox in files
2.  Make a folder for Backups if you haven't done so already and copy all original files into it
3. Go back to the vox folder and delete the bomb.vox file
4. Copy this file in the same folder
(If you want to throw these then just do the same with the preexisting pipebomb.vox file and rename this file pipebomb.vox from bomb.vox)
