About this app

Do you enjoy taking things apart to see how they work? MecaBlocks 3D is an engineering workshop on your phone: you build machines piece by piece with beams, axles, pins, gears, and motors, just like real building blocks, and then watch them move. It comes with 179 ready-to-assemble machines, 84 types of pieces, and 16 lessons. Everything works offline and without registration.

FREE 3D CREATOR
Choose a piece and tap it on the base, a hole, or an axle: it fits automatically, with real-world dimensions. Rotate, move, duplicate, and undo. Add a motor or a crank and tap Simulate.

ENGINEER TESTS
With a single tap, the physics engine checks your design: whether everything fits together, whether each axle rests on two points, whether any gear passes through a beam, whether the teeth are spaced correctly, and whether the mechanism jams. It tells you which piece fails and why.

179 PRE-DESIGNED MACHINES
Step-by-step 3D instructions, with a parts list for each step and a simulation at the end:
• Catapults, trebuchets, ballistae, and siege towers that actually launch projectiles
• Cranes, forklifts, excavators, presses, and conveyor belts
• Cars with differentials, 4x4, steering, gearboxes, and suspension
• Piston engines, Watt, Chebyshev, and Peaucellier mechanisms
• Robots and automata: walking legs, grippers, and arms with worm gears
• Clocks, counters, odometers, planetary gears, and household items
Any machine can be opened in the creator to modify it to your liking.

LEARN WITH REAL PHYSICS
16 short lessons, from a beam and a pin to a complete factory: gear ratios, worm gears, rack and pinion, differentials, connecting rods and cranks, four-bar linkages, levers, and projectile motion. Each lesson includes a 3D model of the machine, a numbered explanation, and a mini-quiz. Earn achievements as you progress.

84 PART TYPES
Straight beams with 2 to 15 holes, thin beams, L-beams, T-beams, and bent beams; shafts with 2 to 16 holes; smooth and friction pins; connectors; spur, bevel, double-bevel, worm, and rack gears; differentials; wheels of various sizes; pulleys, rubber bands, reels, hooks, motors, and batteries. Tap any part to rotate it in 3D and see its numbered holes.

MY BOX
Do you have any real parts? Mark how many you have of each type, and the tests will tell you what you're missing before you assemble them on the table. Otherwise, the box is unlimited.

YOUR DESIGNS ARE YOURS
They are saved only on your phone. Share them as a file with whomever you want.

IDEAL FOR
• Engineering students, technicians, and anyone curious about mechanics
• Physics and technology teachers who want to demonstrate how a machine works
• Those who assemble technical block kits and want to plan their models
• Learning about gears, levers, and mechanisms through play

The measurements follow the most common pin and axle system for technical blocks (1 module = 8 mm).

MecaBlocks 3D is free and supported by a discreet ad at the bottom that the creator never covers.
