So you’ve tried your hand at Dalgona coffee, sourdough bread, and even knitting. You also managed to grow bored with Animal Crossing and watched season two of Dead to Me in record time. What now?

If you’re like most people, you’re probably feeling social distancing fatigue at this point — and we get it. It’s tough to stay sane at home with no social life to be found. Might we suggest you add 3D puzzling to your list of activities?

We’re not talking about regular old puzzles of course (you had those down in month one). We’re talking about crafting 3D creations that are admittedly a bit more challenging but will get your mind working and keep your hands busy. 

Here are some of the things you can create, all of which can be assembled without glue and chemicals:


Featuring a skeleton steampunk style, this monowheel lets you see and gawk over the beauty of moving gears. And while it looks flimsy on the outside, it is actually pretty sturdy. You can even take it outside and give it a good roll around any semi-hard surfaces if you wish.

460 Locomotive

Designed with utmost intricacy, this replica of the 19th-century wonder captures the imagination of all who see it. The model is driven by rubber bands and a gear array in lieu of superheated steam, but its main mechanism looks and operates much like that of a real steam engine.

Treasure Box

This one’s a bit more challenging, but we believe in you! There’s even a working key and all. When the gears are in motion, you can observe their work as they turn and slowly unravel the contents of the box.

U-9 Grand Prix Car

You may not have the opportunity to drive a Grand Prix Car, but at least you can craft one. This puzzle is complete with a V8 engine, fully-functioning valves, transmission modes, rubberized wheels, and more.


This one is an animated kinetic sculpture that looks so real, you’ll feel like it will fly away on its own. Each of its details is designed to make sure it plays its part in the workings of this awe-inspiring mechanism. It can even imitate the flutter of a butterfly with its rubber-band motor.


Lastly, go ahead and build your own safe with a personal lock combination. You can store your items inside and then forget your combination on purpose. You then follow the steps in the instructions, which will have you master the mix of slow knob twists and careful listening to tumbler movements that will open the lock. Sherlock Holmes wannabes, this is for you!
