Jānis Ozols, author of the idea, says not much is needed.
“You can come anywhere, quickly set up, and get started. I bought this [printer] for around €300, but nothing is original, everything has been rebuilt, said Ozols, who runs the 3D Savvaļas Bites page on Facebook.
The product shall be attached to explosives in Ukraine. Currently, two types of “tails” are printed, for two different types of explosives.
“They have models of different grenades. This is VOG-17 and this is VOG-25. Its tail attachment places and width are different, so we make different ones. The grenade is spun and it doesn't start rolling down when it falls. If it falls sideways, then doesn't burst. “It has to fall straight to a solid object,” said Ozols.
A single print requires 40 minutes. Currently, around 10 people are doing it. Everyone does this on a voluntary basis, buying the material they need for printing. 100-item printing consumes electricity at approximately €6.
“At first I wanted to make drones and send them in a ready-made way to Ukraine, but since the parts weren't available, I started looking for other options as I can help,” Ozols said. “Most of us are people who have 3D printers at home. A total of 20 printers. We asked the Ukrainians how we could help. [..] They asked for a lot of tails, hundreds. We're making thousands."
Where the tails go and how they can be printed, you can find out the volunteers on the 3D Savvaļas bites page on Facebook.
