Odd values are -=1 eurorackMountHolesTopRow(php, hw, holes/2); eurorackMountHolesBottomRow(php, hw, holes } module make_surface(filename, h) { for (a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]) linear_extrude(height=a/h, convexity=10) projection(cut = true) surface(filename, center=true); } // there's an arrow shaped hole you can have. There aren't a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled clock. Presumably the CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock.
