Joel Telling remixed with tf2's engineer, for obvious reasons, I mean come on, he was holding a wrench already.
All of the additional models have been created by me, the wrench and hardhat being my first blender models, the sentry was done in FreeCAD.
It is not easy to print and as you can see in the cover image, mine failed spectacularly when i failed to think about how i was gonna remove the sentry's support materials, but i ran out of time to reprint it or make modifications.
There are 2 models, LQ or low quality makes the sentry slightly more bearable to print by making the gun barrel filled in and thickening the front legs, its still not great though.

Yes, the sentry has a pair of goggles on it's head, it is intentional, i found it cute
