Real engineering uses standardized components. InventShack kits work the same way — laser-cut panels, 3D-printed connectors, and standard hardware that combine into any build you can imagine.
Unlike toy kits where every piece is unique and single-purpose, component-based kits use standardized parts that follow engineering principles. The same type of screw, the same material thickness, the same connection system — across every build.
This means kids learn transferable skills. Understanding how a tab-and-slot joint works in a car chassis means you already know how it works in a catapult frame. Mastering M3 screws in one project means you're ready for the next one.
1/8" birchwood plywood, precision-cut up to 12"x12". Tab-and-slot joints with 3.2mm minimum slot width for reliable assembly.
Custom PLA components — brackets, axle mounts, gear housings, spring seats. Minimum 1.5mm wall thickness for durability.
M3 screws (8mm, 12mm, 16mm), hex nuts, washers. Standardized across all kits so kids build familiarity with real fasteners.
Rubber bands (various sizes) and compression springs. These store and release energy for moving parts — cars, catapults, and launchers.
Laser-cut panels interlock with precision tabs and slots. The primary structural joint — strong, reliable, and satisfying to snap together.
M3 screws pass through 3D-printed brackets to secure panels. Kids learn to use real tools and fasteners.
3D-printed bearings hold axles for wheels and rotating parts. Smooth rotation with minimal friction.
Tight-tolerance joints where parts friction-fit together. No hardware needed — just push and click.
Rubber bands stretch between 3D-printed hooks. Stores elastic energy for cars, launchers, and spring mechanisms.
3D-printed cups hold compression springs in place. Used for pop-up mechanisms, shock absorbers, and launchers.
Working with modular components teaches kids to think like engineers. Instead of following a single set of instructions, they start understanding systems — how parts interact, why certain materials are chosen for certain jobs, and how changing one component affects the whole build.
This is the same kind of thinking used in real engineering, from building bridges to designing robots. The scale is different, but the mental model is the same: break a problem into parts, design each part, then assemble them into a working whole.
