This is more of a general one, but I think the sometimes arguably horrific colour-coordination on some sets could be a thing to look at . Good example of this is Kopaka’15’s silver toros piece, which makes no real sense at all compared to his otherwise white, gold and transparant blue.
and in terms of masks, can we please get masks that stay on unless you actively pull them off, and not where you look at them wrong and pop they go?
Step 1: While you are developing the parts you need to mold for the next wave of BIONICLE? Make sure the gearbox is made so that there is a balljoint on the front that will attach an armor shell while not being very gappy
Step 2: Use TECHNIC pieces to connect Vahki waist to gearbox
The Vahki waist connects to most models via an axle hole in the side.
The TECHNIC piece in question has an axle hole perpendicular to two pinholes that can connect to the gearbox as is (and presumably would be on my modified gearbox idea as well.)
