Designing the Screwdriver
Q: What sets the LTT screwdriver apart?
A: It’s a durable, ergonomic multi-bit ratcheting screwdriver with unique features like in-handle bit storage and a strong magnet, based on a modified Megapro design.
Q: What was your role in the project?
A: As project leader, I oversaw the three-year process, using 3D printing to create prototypes for Linus’s feedback.
Q: What was the state of the project when you started?
A: We had an idea and a rough handle model by Alex Clark, iterated with 3D-printed prototypes on a Prusa MK3 for Linus’s input.

3D Printing Impact
Q: How did 3D printing help?
A: It allowed rapid iteration, producing 7-8 prototypes weekly, cutting development time and costs significantly.
Q: Does 3D printing make sense cost-wise?
A: Yes, it reduces prototyping costs, enabling more iterations and avoiding expensive failures, aligning with business cases.
Q: Will FDM prints be final products?
A: It’s happening—print farms sell 3D-printed NERF accessories, though it’s not our core focus yet.
