Hand crank can chiller V2

Cool your drink in 2 minutes!

You do need to freeze some water in a tub, but if you place it back in the freezer after use you will always be able to cool a drink really fast. 

Place your can on the ice, turn it a bit by hand to melt a groove in the ice. Then continue to spin the can on the ice with the hand crank can chiller. 2 minutes is cold, 3 minutes is really cold. See pictures.

How does this work? The melting water acts as a bearing between can and ice, making it spin easy and cooling down the can at the same time. Because it spins the drink inside wil be moving around keeping the thermal difference between drink and ice the biggest wich in turns gives the greatest cooling effect. 

Hardware list :

2 X Skateboard bearing  22mm OD, 8mm ID and 7mm thick
4 X Hexbolt M8*40MM
3 X M8 Cap nuts
2 X M8 nuts approx 6.5mm thick.
1 X O-ring 54.7mm OD, 47.7mm ID ,with a section size of 3.5 mm

This version does not utilize shims for fitting the bearings but instead has a hole diameter of 22.08mm wich gives a snug fit on my machine. Step files are included if you need to change the clearance. 

Even with a snug fit it is adviced to use CA glue to attach the bearings to the printed parts.

Print instructions : use 4 walls on all parts.

Assembly,

Please see pictures for reference.

First press the bearings in the bearing houssing. 

Then screw the stationary handle to the center of the bearring houssing, to prevent the need of support material there is a single layer of plastic closing the hole. Remove this first. 

Screw an m8 bolt through the off-center hole in the big gear, slide on the rotating handle and ad a capp nut. Make sure the handle can rotate freely on the bolt. 

Now put the m8 bolts through the bearrings and screw on the nuts tight.

Place the o-ring in the groove of the wheel and screw the wheel to the bolt, add the cap nut to secure it. (see pictures for mounting direction)

Repeat for the big gear. 

And you are done! Now just keep a tub of ice in your freezer and you will allways have a nice cold drink in 2 minutes ! Cheers!
