Magnet Testing

9V – 50 N Electric Lifting Magnet

Pros
  • Overall size: 25 x 20 mm
  • $ 13.49 + tax
Cons
  • Lack of penetrability through 1/8” MDF

12V – 400 N Electric Lifting Magnet

Pros
  • Can penetrate through 1/8” of MDF
Cons
  • $ 17.99 + tax
  • Overall size: 49 x 22 mm
  • Use of three neodymium magnets will produce a strong enough magnetic force to hold onto the steel door through a 3/32” wood veneer.

Neodymium Bar Magnets

Pros
  • Can penetrate through 1/8” of MDF
  • Replaces the wiring through the jig
Cons
  • Needs to be handled with care

Hinge Testing

3D Printed PLA Hinges (Friction fit)

Pros
  • Prints in place, easy to manufacture
Cons
  • Not securely mounted onto the rest of the components
  • Friction fit wears out
  • Each layer was difficult to print

Hinges (Bolt + Nut)

Pros
  • Moving parts will not wear out by friction
  • Can be disassembled in the event of a component needing repair
  • 100% infill makes the component sturdy
Cons
  • Getting the hinge to move when first printed requires an adequate amount of force

Infill Testing

Hinge Midpiece (Lightning infill pattern)

Pros
  • Printing time was reduced, even at 100% infill
Cons
  • Sections that did not have the hinge were hollow
  • Would not survive day-to-day wear and tear

Hinges (Bolt + Nut)

Pros
  • Solid and feels higher quality
  • Won’t break when pressing into it
Cons
  • Longer print time
  • More filament used
