Keycaps v2: C64 75%, C64 add-on, plain and blank sets

Exports of the design at commit 9ef9f89, made 2026-10-25. The set grew from one C64 75% set into four sets for ANSI boards from 60% to full size, and each set is now its own download: a 3MF to slice and a STEP to open in CAD.

Set	Files	Caps	Export
C64 75%	c64-75.3mf, c64-75.step	81	7ce64e81
C64 add-on	c64-addon.3mf, c64-addon.step	37	85627423

• C64 75%: the original set, dark brown with cream legends and PETSCII fronts.
• C64 add-on: C64-style caps for other boards: TKL nav cluster, 17-key numpad with a stacked RETURN, full-size right mods, Tsangan mods, 7u space.
• Plain: full-size ANSI with standard PC legends, plus extras for Tsangan, 65% and 75%.
• Blank: full-size ANSI with no legends, plus extras.

In the 3MFs every cap is one object with its legend inlay as a second part, ready for a second filament. The README has which caps to print for each board size and printing notes.

Unlike v1, there's no ZIP package with per-part STLs and no BOM in this release.
