Looking for a striking GBC module ? Then Stamp GBC module from Takanori Hashimoto is what you’re looking for. The main articulated arm of this massive GBC module delicately catches up your GBC balls to take them one by one to an exit ramp. An LEGO Technic axle moving up and down prevents the balls from leaving the exit ramp. The main arm moves extremely smoothly, in total harmony and synchronisation with the movements of the LEGO Technic axle. Once again a very inspiring GBC module from Takanori Hashimoto, which you can reproduce and add to your GBC collection thanks to his building instructions.

  1. Are the instructions for sale to build the original or improved version or both versions?

  2. I have completed this build, but I find it incredibly frustrating to get the timing to work correctly. I may get it to work for a few balls in a row, but then it goes out of sync again. Any hints to getting it to work?

    1. Is it skipping teeth?
      Do you get a clicking sound?

      I made some adaptations to this module because there was too much resistance in the mechanisms.
      The adaptation made the whole thing move freely. If you want to know what I did, let me know.

  3. Step 369 is very confusing, is there an error? I don’t understand how the L-arm mounts

    It’s a 5 x 3 L shaped lift arm and it fits externally. It holds the chute at 80 degrees (if you want it in that position).
    The centre of the 3 part of the lift arm pins to the top hole of the 13 x studless beam.
