another quick exercise, I should call them "life modelling", i guess.
well, not so quick this time, the joint on the cap was really a nightmere :D
No materials this time, i wanted to focus just on the modelling. There's a shape key to use for opening/closing the cap. it's not really well made, so you'll have some issue if you need the cap to be half open, but if you just need it fully open or closed it works fine.
