Model origin

The author remixed this model.

Differences of the remix compared to the original

🔥Small spacers to operate the original version with ballpoint pen springs🔥 

 No need to buy a large spring or make any other adjustments (no glue or lubrication required).


What you need: (2 versions possible, please measure the inner diameter of the spring) 


✅  2x the spacers (or more if the spring is too short!)
✅  4x ballpoint pen springs

Once the springs and spacers have been inserted into the guide, the springs must protrude slightly from the guide when untensioned (see picture), only then will the mechanism have enough force to function properly. If the springs are too short, insert more spacers!
