I've made dedicated "travel axles" by taking the axles, cones and locknuts out of defunct or damaged hubs (free at your LBS if they like you). Thread on the cones and locknuts and adjust and tighten them so the OLD is correct (100 mm for a front and 126, 130 or 135 as needed for a rear ). They stay in place using your qr skewer or axle nuts.
