In Fusion 360, I created a sturdy screwdriver design featuring built-in bit storage for six hex bits. To ensure durability, I reinforced the bit holder by printing it with 100% infill, providing maximum strength. For the remaining components, I opted for a 15% infill, striking a balance between robustness and material efficiency.
During extensive testing, the screwdriver withstood all my efforts to break it, demonstrating exceptional resilience and performance.
Note - If the sliding mechanism is too loose I have provided an updated version which solves this issue
