V6 GEARBOX (6x 775 DC Motors)

This video is viewer suggested. When two months ago I build this same thing using 8 micro motors then this time it's upgraded to 775 DC motors. In design, I made a lot of improvements. For testing, I attached this new gearbox to a water pump and snow blower. This 900w gearbox has a lot of power...

LILY IMPELLER PAINT MIXER (LETS PRINT YOUTUBE CHANNEL)

VIDEO: https://youtu.be/h2bTrvCoMYU

I think this is the most useful print that I have ever made. I work a lot with paints and celar coats and this really simple print makes my life way easier and saves me a lot of time. This paint mixer will literally have practical use in the real world. 
I was really excited to use and print the lily impeller, I was amazed by how well it did work.
