Hard Surface Modeling during my learning phase (still learning about Hard Surface modeling).
Special thanks to BlendBros and @PonteRyuurui and @joshgambrell for their amazing tutorials for Blender Hard Surface Modeling.
Their guidance and tutorials are the best way to learn Hard Surface Modeling in Blender (Using add-ons such as HardOps, Box Cutter, Kit-Ops, Decal Machine, Mesh Machine, etc).
Many of these are the results after watching their YouTube tutorials. Some I adjusted to be my own either with textures or styling, etc). but the basis is the result of their teachings.
