This 3D start button for Transformers consists of a single continuous 3D print with mid-print filament changes so the entire pattern is fused together.

The 2011 version used a smaller, recessed start button, so this item includes a full housing assembly that covers up the counterbore in the cabinet for a clean installation of the new, larger button. (See pics.)

The 2026 version uses a large version of the start button, so only the button cap will be included; housing is not required.

Available in Autobot (“Roll Out”) or Decepticon (“Rise Up”), in the listed translucent base color options.  Red and purple buttons include a colored bulb matching the button base, for a deeper/richer color when lit.

It’s easy to install — NO SOLDERING REQUIRED!  See installation videos for DIY instructions.
