2x – 6mm ID. 15mm OD bearing (had these laying around) find what you can, modify the files as necessary.
1x - 60mm shaft 6mm diameter (matches the bearings)
12x - wood screws
1x plank of wood. Approx. 12inch x 16inch
3x Spacer wood 2x4 is what I used.

EDIT: after a few questions the motor I used is built by globe motors, however it has an HP Part number of "02566 - 60448" I included the SKP files on this design so people can adotp it to different motors. I suspect nearly any 25-40RPM geared DC motor would do, within reason that is.
