01 / BUILD LOG

How it got made

Every step, in order. Click any photo to zoom.

  1. 01

    Frame the dome

    A real shield isn't flat. The first job was building a curved skeleton: wedge-shaped segments meeting in the center, like an umbrella.

    The dome skeleton on the floor surrounded by tools
  2. 02

    Skin it, then add the rings

    Panels go over the frame, then a raised ring and star outline are built up on top. Tools and offcuts everywhere.

  3. 03

    Carve the star

    The center gets cut into foam: one circle, one five-point star. This is the part everyone looks at, so the lines have to be clean.

    Oct 11: hardware store run for spray paint.

  4. 04

    Test fit

    Parts cut and painted separately, then stacked to check the fit before anything is glued for good.

  5. 05

    Stencils + spray

    Paper stencils for each color. Spray inside a cardboard box so the paint lands on the part, not the apartment.

  6. 06

    Mask, paint, repeat

    Finishing touches. Tape off the rings, hit them with paint, peel, check, do it again until every edge is crisp.

    The mount: magnets

    The engineering part. Magnets on the back plus adjustable belt straps, so the shield clicks onto a harness and comes off in a second. Arm or back.
