Small Gear Sets:

All small gear sets are the same size, 20 cm x 20 cm (~7.75 inches x 7.75 inches).
Each gear set explores a theme and packs as much into the gear set as possible.

• Compact gear set:  Designed to be used as a first gear set.  Can stand alone or be combined with other gear sets for more options.  Has as much variety and options as could be packed into it.
• Hoops gear set: A collection of nested hoops from 32/16 all the way up to 176/160 in increments of 16.  An excellent companion to the Compact gear set.  Adds a huge amount of design options but only has one gear of its own.
• Encyclopedic gear set: Has ever gear from 12-30 represented in several forms.  Introduces tiny pen holes (~1 mm diameter) as well as the pen holes that are aligned with the gear tooth, and identical sets that are aligned with the gap between gear teeth.
• Small Drops gear set:  A collection of drop shaped gears, a specific type of non-circular gear.
