It Works! 3D Printed Toyota Transmission

Maker genius strikes again! With access to a 3D printer and shared files, now you can print a working five-speed transmission and engine. This video from maker and car aficionado Eric Harrell shows a transmission for a Toyota 22RE engine printed to about 1:3 scale.

Full-scale, the Toyota 22RE engine was produced from 1981 through 1997. It’s found in vehicles such as the Celica, 4Runner and Corona.

Of course, this plastic version can’t handle gasoline. Go green! We suggest patented Modarri finger-steering.


Download the files The Toyota transmission file can be downloaded from MakerBot as Thingiverse item number 713815. The engine is file number 644933.

Cars Write to Astronaut Dad

Stephanie in Houston, TX missed her dad a lot in January. He was floating in a tin can, the International Space Station. That’s outside of Verizon’s service area… but with help from 11 cars, she messaged him in a new old-fashioned way.

On January 18, a fleet of Hyundai Genesis cars hit the Nevada desert. Writing Steph’s message in the sand, they made her dad’s day!

The cars also broke the Guinness World Record for “the largest tire track image.” The note measured 59,808,480.26 square feet.

Inspired by the big cars, we’ll test our Modarri toy car handwriting (tirewriting?) next time we hit the beach!

Best Free Apps for Road Trips (Part One)

Here at Modarri toy car headquarters, we generally recommend that drivers unplug-and-play. “Feel the road!” Even so, apps are handy when you’re cooped up on road trips. For entertainment and getting useful info, here are some favorite free apps for the road! Each app mentioned here has earned four or five stars in overall user ratings. Plus, we tested them all for user friendliness.

GasBuddy_free_app_for_driversGasBuddy by GasBuddy Organization

It’s crowdsourcing for cheap gas! GasBuddy is a free community app dedicated to finding the cheapest gas possible.

How it works: Users update gas prices in real time. Using this info and your GPS data, the app will suggest where to fill your tank.

Win fuel: For each gas price that you report, you’ll earn points toward prize giveaways. A $100 gas card is given away every day.

Google Maps by Google

An obvious choice for most lists of road apps, the free Google Maps app rarely lets us down. Google Maps offers turn-by-turn navigation plus route previews and maps showing traffic congestion.

Google Maps will also make local restaurant suggestions — now tailored by cuisine — and can display the weather forecast for any destination.

The License Plate Game by Joseph Levine

Family fun! Keep track of which US license plates you’ve seen. Sure, you could do that with paper and pencil – but license plate apps offer lots more. Of the free options, The License Plate Game by Joseph Levine is our favorite for iOS.

The License Plate Game app lists the fifty US states and shows a sample license plate from each. Tap a plate to check it off. Besides that you can:

  • Add photos of “special plates” that you spot, such as those from outside the US or from Native American tribes
  • See how common each plate is. Each state gets a difficulty rating based on how many plates are on the road. For example, California license plates have a difficulty rating of “Easy.” There are supposedly 32 million CA plates. Hawaiian plates, on the other hand, are rated “Very Hard” to find. There are only 959,000 of them on the road, according to the app developer.
  • Get statistics about the percentage of US plates you’ve seen.
  • Pin the location of each sighting. This option can be turned off if you’re not a fan of geo-tracking.

The screen is cluttered when you first open the app, but after you clear the simple instructions it looks great. Unlike other license plate game apps we tried, it’s easy to use and not full of distractions.

Stone Age Toy Car

It’s the world’s oldest known toy car!


Toy cars seem to be as old as the wheel. This miniature car, probably meant to be a chariot, is made entirely of stone. It was unearthed during excavations in Kiziltepe, Mardin in southeastern Turkey. Archaeologist Mesut Alp estimates that it’s 7500 years old.

Stone dolls and whistles were also found in the area. We love imagining the old-time toy inventors!

Other wheeled toys from the Stone Age have been found, but this is the first with four wheels like a modern car. It’s not all that different from a 2015 Modarri! Here it’s alongside our ready-to-paint Modarri DIY Car.

The Stone Age toy car is now on display at the Mardin Museum.
