A multicolour sampler that is genuinely useful on an arm build: print each link a different colour to make assembly and wiring obvious, add bright accent parts, or just test colours before committing to a 1kg roll. Eight individually vacuum-packed 250g spools keep unused colours dry. Same printable PLA, in a format that suits detailing rather than bulk structure.
