Catch Tile
This tile is still in development and is not tuned properly yet to have the exact intended effect. Print at your own risk! I will update the arm when the tuning is complete.
This is a new tile for Hextraction that I made. The idea is that balls will be stopped by the lever arm until there are enough for their weight to lift the arm and release multiple balls. If it is weighted correctly, balls with different speeds will get different behavior, which is pretty cool.
I designed the joint to use a 3mm OD x 20mm screw, but using a 3d printed cylinder that is glued into the hole could also work.
The arms will lift too easily without weight. Glue a ball to the end of the arm to add weight.
All models are scaled up 10x.
Thanks and have fun,

Got this tile working well by adding hot glue to the underside of the middle arm. Here is a video of it in action. https://youtu.be/brUEhrb0i3o?si=o94JaUc03ZiBAt2l
Why are those models scaled up 10x?
Added a mod for the arm- feel free to incorporate into the original if you wish: https://than.gs/m/883381. This is now one of the fav tiles from the group I've been testing with- thanks for the design.
Thank you!
I love the design, and printed a couple last night. Definitely need to add weight to the arms... will experiment on making a mod for this tonight
