That wood crate should be fine at the low temp you'll be using in the oven. It's nailed, not glued, so it won't melt and fall apart, which is the main concern with wooden crates/molds. And you're only heating to about 170F, so it's not very hot, actually. Cardboard will be fine in that as long as it's not touching the actual heating element.
