stackable storage box (fast print 30 min)

I created these storage boxes so I could sort my L E G O, because I couldn't find a suitable model on MakerWorld.The alternatives available on the market were also more expensive than the cost of the filament and electricity.I tried to make the printing as fast as possible. If your printer isn't very stable or you want better quality, simply change the wall generator mode to classic and reduce the printing speed.
