[3D Printing]  What are some good 3d printed gimmick ideas you have?

Infinite Lock is Probably GT exclusive like Burst Stopper was to Cho-Z. We could see a variation similar to it tho.
I would say sharp rubber attack points with 3 to 6 bladed modes.
a left rotating bey with rubber and a bound gimmick so it springs when the same rotation bey comes at it but doesnt when right spinning beys do maximizing spin stealing and minimizing damage
Remote control beys that you can press a button for it to switch modes like mode 1 normal mode 2 berserk mode and it starts moving like crazy 3 stamina mode goes to the center and stays there to recover
A super effect gimmick would be similar to what crazy aries did with the L gear design. Make a Lucifer with a blade that is both free spinning and has the rubber shield like variant. It would be much more effective.
maybe a sliding blade that moves one side in and the other out.
can you help me guy
