Cauldron Crab Droid by Colin. Nice use of color here.
Killbot (Anti-Mecha Drone) by Darkspawn. Those leg pieces are pretty rare.
Rhino Beetle Mech by the masked-builder. This one is outstanding.
Generic Droid by Maelven. This is tight. It may be a little
flimsy though as I've found the ends of those
Minifig Handlebars to be unreliable connection points.
Orange Crab by ~J6Crash~. My heart fills with joy
at seeing this. Technic part use like this is fantastic.
