Brake - Attached to a piston and had a short length of 25 chain captured in it. It was thrust onto a sprocket to stop our hab from moving when we didnt want it to. Went through many iterations before the chain with a simple triangle shape, a smooth curve, a roughened curve with a sprocket shape cut into it and finally a captured piece of chain.
Cylinder mount to a 1x1 square tube
Linear slides for our intake. one of the square cutouts is a tight fit, one is a loose fit for the sliding motion.
Front and rear hab wheel assemblies. Before we automated our HAB climb we replaced these quite often, 3D printing was a great decision to both allow them to be the first failure point to protect the robot and allow for easy replacement
More 1x1 tubing linear slides for our hatch grabber. The bigger piece in the front also attached to the cargo holder and served as the main bracing for the cantilevered hatch grabber. Went through many iterations and also many replacements as it took the full force of the weight of the scoring mechanisms the few times our lift came crashing down.
If anyone has any questions about a specific part I can provide some better screenshots.
