Technical Building Blocks Accessories Set, Good Compatibility with Major Brands

A 544-piece grab bag of technical bits — beams, connectors, wheel axles, tires, and a pullback motor. Useful for replacing lost parts or adding motion to custom builds.

This is a bulk kit of 544 technical parts. You get liftarms and beams, connectors, replacement wheel axles and tires, plus a pullback motor to add movement. The set is listed as compatible with major brands, so the pieces can join existing sets or live in your MOC and custom-build stash. Handy when you need spare wheels, extra connectors, or a simple motor to make something go. It’s a parts pack, not a finished toy — you still have to build the fun.
