V-Blender for powder mixing (usb-c power)

This is a small V-blender (~600 ml) for powder mixing.
V-blender are used for powder mixing in many industries (like pharma and food), It is a very simple concept and i was surprise to see that there is no 3D printed v-blenders online, i took this opportunity to make one with the help of Samuel Gravel from UConn.
My lab at UConn uses powders a lot, so having this tool is great!
The volume is about ~600 ml meaning you can use about 250 ml of powder in this to mix them together.

This need a couple of things that can't be 3D printed.
1 - rubber band
1 - 40 rpm 5v dc motor (https://www.aliexpress.us/item/3256806174791860)
1 - usb-c power connector (https://www.aliexpress.us/item/3256806449080976)
1 - switch (https://www.aliexpress.us/item/2251832872323782)
misc wire and soldering kit.

Make sure to clean it very well, try to get the internal of the v-blender as smooth as you can, to make sure that the powder doesn't stick too much to it.
