SendCutSend instructions for getting metal mount created

Since I've never used SendCutSend before, it'd be nice to have a step-by-step set of instructions for ordering the 2U faceplate in metal from them (mostly what options to choose), and notes about potential costs and shipping times.

(There is no rush to do this of course!)

Separately, maybe someone in the community would like to organize a group buy? Logistics mostly kill that sort of thing, but if multiple people in one small region might want metal parts, it would save money to have one person order multiples, then distribute them locally.

And with flat 10" parts, shipping costs aren't that bad.

Empieza por revisar la documentación existente del repositorio sobre la placa frontal 2U y cualquier indicación actual sobre SendCutSend. Documenta las opciones de pedido, los posibles costes, los plazos de envío y cualquier nota sobre compras conjuntas que esté claramente respaldada; el trabajo estará terminado cuando un lector pueda seguir los pasos para pedir la pieza metálica.
