Advice on a waist design for my Makuta. Preferably as wide and long as a 2015 gearbox. I just realised how little time I have left and I still need his weapon, arms and a way to connect osome wings (possibly) and after a week I still can’t think or a waist design. No function wanted really. Thanks in advance.
That depends entirely on your parts collection. However, as some advice, drop the friction extender (or don’t) and swap to one bone length longer, which will give you a Technic pin hole to work with. That small change along should be enough to give you the ability to add the bulk you want.
The arms are really bad, you should just use the same parts you used for the legs.
Also you should use the smaller bohrok feet parts these seem kinda big, but the matoran them selves are kinda weird in proportions anyway.
