Dispenser for Potion Explosion

NOT FINISHED YET / I'm still working at it ! Don't print if you don't want to lose time and money.
Or print and report me to help me to fix.
UPDATE : I reworked it and I made some fixes about bad diameters.
This is still a prototype, but it should be close to be finished.
I modelized this because my dispenser is worn. Splitted in 2 part, to allow printing on ~200x200mm bed.
I re-used the handle of this thing : https://www.thingiverse.com/thing:2120589
