The Akiyuki Project

From The Great Ball Contraption Wiki

The Akiyuki Project is a thread on Eurobricks with "the goal of creating and/or finding complete...instructions" for the GBC modules created by Kawaguchi Akiyuki.

This article organizes the results of that collaboration for easy reference.

Catch and Release[edit]

Catch and Release


The version below contains 717 parts. This is one of the smallest Akiyuki modules, costing less than 100 USD to build.

Models and Instructions[edit]

Adjusting and Timing[edit]

  • The model is somewhat sensitive to the rubber bands that are used. Blakbird used a doubled up blue band and found that it was too tight so the downward force was not enough to force the jaws open. He used a small white band looped over only two of the three fingers instead. The module works very well once adjusted.
  • There is no timing to set on this module.


  • jesuskyr did the builk of work the reverse engineering the module and creating the LDraw model and instructions.
  • Blakbird tested and tuned the replica. <--- like a category --->
