Why was God so specific about how to make the Tabernacle?

The Book of Exodus (ch (https://www.biblegateway.com/passage/?search=exodus+25&version=ESV)–(https://www.biblegateway.com/passage/?search=Exodus%2027&version=ESV)) spends quite a bit of time describing how to build the Tabernacle, right down to the type of metal and wood to use for minor parts, all straight from the mouth of God. Why did God go into such great detail about seemingly trivial matters? Besides the obvious reason of, "It was important," what reasons have published Christian commentaries suggested for the amount of text devoted to a physical description of the Tabernacle?
