Construction of the Sentry

Construction

Constructing the physical sentry I made based off the actual sentry, although with some changes. It's pretty big, though not accurate to the game where it's half the height of a human.

Building and Materials

The sentry's main material is cardboard. The reason being is I had a 2 big pieces of cardboard, and I've made things out of cardboard when I was younger, so I know how to do it without needing expensive tools. Plus again the focus was to learn the STM, not learn how to construct or model things.
The pipe in the middle of the sentry is made out of PCV pipe and steel piping. There are nuts and bolts and the feet are styrofoam which I plan to place rubber underneath.

Challenges

I would say the main challenge was the sentry being top heavy and sentry top portion will rotate backwards along the bolts attaching it to the base. My first iteration I attempted to make a sort of stand to have the metal piping touch the floor or wherever it was placed. This didn't work for long, it eventually tipped if it was slightly moved. I realized I need to connect the center piping to something that was heavier then the top to keep it in place. I thought of sand or clay. I went to home depot and found they sold 5lb bags of sand, which was perfect. I also needed a wide but low in height container to pour the sand in. Luckily my mom had a container shaped just like this from some special tape she bought that was in the container. I removed the tape and put the sand in. This worked much better but another issue I have run into is the sand is too loose, so the sentry can flip a bit. It might have been better to use clay. Something I can maybe try in the future.
