I've made a free Minecraft Fabric mod for 1.21.5+ which lets you craft vehicles with blocks in them (boat with chest, minecart with tnt, etc.) back into their separate parts! It's simple but useful and it's only necessary server-side.

I designed a custom firefly toy brick model. If you want one of these guys for yourself, you can get the instructions PDF for free on my Ko-fi page. Have fun putting it together, and show me your lil guy if you make one!
