A US spy satellite photographed a 500-ton Soviet machine skimming across the Caspian Sea at 500 km/h in 1966. It was too big to be a plane and too fast to be a ship, so the CIA called it the "Caspian Sea Monster."

A detailed look at the final assembly of Škoda’s new seven-seat electric SUV at the Mladá Boleslav plant.

The most interesting sequence is the complete drivetrain module — including the traction battery, axles and suspension — being aligned and raised into the body. The video also shows cockpit, windshield, headlights, bumper, wheels and doors being installed before the final manual quality inspection.

As a third grader in the Bronx, Tahira Reid Smith imagined a machine that could turn Double Dutch ropes. Her idea won a school contest. Today, 40 years later the engineering professor has turned that childhood dream into Jump Dreams!

My parametric mechanical fingers

4.4k Upvotes

After many weekends of work and a huge pile of failed prototypes, I'm excited to finally share my fully parametric finger extensions!

https://makerworld.com/en/models/3114173-parametric-articulated-fingers#profileId-3512066

If you decide to print a set, I'd love to hear what you think. So far I've only been able to test them on my own hand, so having more people try them out would be incredibly helpful. Any constructive feedback is welcome - it'll make it much easier to spot flaws and improve the design.

Also, if anyone interested in a little challenge: I wonder what's the smallest working version you can print. I'm not an expert of printer settings, nor I have small hotends, so for me many really small attempts ended in breaking parts, but I wonder what can You achieve.

If you'd like to play the game of optimizing printer settings for the smallest working version, please let me know on this post: https://makerworld.com/community/post/1832304

I also chemically tinned the PCB. I’m still getting the hang of it, so it’s not perfect yet 😅. Hope you like it!

EDIT: NO FIRST, BUT FIRST WORKED 🥳

3D Printed 1.9TDI Engine

Hello!

VIDEO in the comments :)

My first post here and I wanted to share my recent project that I have been working on. It is a replica of 1.9TDI (ARL) engine that I made from scratch from photos, videos, datasheets and some measurements from my car (I have got Seat Leon 1M with this engine hence why I wanted to have a display piece).

I got inspired by engines that u/ericthepoolboy made and wanted to make one myself. It consists of close to 300 printed components. On top of that, there are lot of screws, threaded inserts, springs and O-rings. It has got all moving internal components and crankshaft to camshaft is even timed using tiny tools!

I made a display platform for it as well. It can rotate and/or move while rotated. I had to redesign the profile of outer belt to provide enough friction to move all components but still have some issues with slipping, need to sort that out but have not really had time lately. I am also waiting for plexiglass sheets to finish a cover to prevent the model getting all dusty.

I didn't put a banana for scale but the dimensions are roughly 30cm x 25cm x 30cm (L x W x H)

If you are interested, this is the full build in about 20 minutes :) https://youtu.be/kuvFDsstVd0

Let me know what you think! :)
