This bead roller allows you take putty, clay, or similar, and make spherical beads like any professional bead roller. The parametric variables can be changed in the Customizer so you can make many beads of the same size at once, or have a single block capable of making up to six different bead sizes.

This model was inspired by the commercial products but the tracks at the edges were purely from seeing the 20mm model by DrPeper. All code was new, and the parametric aspect was an improvement.

It is important to increase the Half Block Thickness if any of the tracks are over 13mm.

Please note that the variables are for the hole radii, not diameters. Most beads are measured by their diameter, so be wary.

Zero is an acceptable dimension for a track if you don't want to waste filament.
