This is an awsome unit. I designed it to utilize a large mouth ball jar for the top container and two 608 bearings for the rotating arbor dispenser. The regular arbor dispenser sends out about 10 MnM's which is perfect. But I included a large and XL size as well. You will also need seven M4 x 10 SHCS and one M3 x10 with and type of head. The base, faceplate, and retaining washer use the M4's and the bowtie handle use the M3. I made it with the m3 just to not have a huge bolt on the handle. And technically the retaining bolt isn't even necessary since everything is “pinched” between the faceplate and main body.

I also printed the faceplate face down to use a “textured” style plate. (The one with all the colored circles). But you don't need to print it that way. But either way will need supports.
