A retro handheld console, sized to your board

A Game Boy-style two-shell console around a known board — the shell grows to fit the board, screen, battery, charger and speaker you pick, with the D-pad, A/B, start and select already laid out. Pick the board, generate, print two shells.

What you get

  • A face lid with the screen window, button holes, speaker grille and rounded grips
  • A back bay with a dimensioned mount for every part — standoffs for the board, a cradle for the cell, a pocket for the charger
  • Wall slots for the board USB and the charger USB
  • Print files (one STL per shell) and a plated 3MF, engineer-checked

Pick a layout

Each preset opens the Form with the description and parts filled in. Generate as is, or edit first.

Customise without losing the layout

After the first result, the refine chat changes one thing at a time and keeps everything else — the button positions, the mounts, the shell proportions. Things people say:

  • "two 18650 cells"
  • "LiPo pocket instead of the 18650"
  • "add X/Y buttons in a diamond"
  • "no speaker"
  • "black PETG"
  • "3.5-inch screen" (the shell grows)
  • "move the speaker to the top edge"
  • "3.5-inch screen"
  • "add X/Y buttons"

Then print it, or have us build it

Every finished design shows a slicer-confirmed print price and an Order this print button. If you would rather not assemble it yourself, Ask Microscale to build this on the result page opens a Build engagement — parts gathered, shells printed, unit assembled — priced within one business day.
